Preface:​

I have no involvement with the company, purchased this product for full MSRP on pre-order. This post is meant to discuss the unit's capabilities and impressions after using it for couple of days. The idea is to expand and update (& correct) this post with feedback from others who have experience with the product.

Some good tech and workflow info from razorback here:

Rumors began flying in early '24 about a new WMLRF coming out later that year. This was eventually confirmed when a few posts surfaced on social media and @DocUSMCRetired himself confirmed the unit's existence later in the year here on the Hide. With options limited for years to essentially a Raptar, Radius & STORM or recently MARS, MRF and Vortex 4000. With some major downsides to most of those options, new WMLRF with onboard Applied ballistics just north of a $1000 was a fairly exciting proposition. Despite sour taste from a few pre-orders in this industry in the past, I obviously learned nothing & went ahead and got on the list. Orders were taken in late December '24 with full price paid upfront, ETA from Tango Innovations was 2nd or 3rd week in Jan '25. They only missed the deadline by about a week, with email communication on the original deadline stating as such. Shipping was upgraded to expedited as a result for everyone on pre-order free of charge. Good on them in that respect, no gripes from me.

What arrived:


Well packaged unit with remote button (4 pin connector, fisher maybe?), some zip ties & zero-ing reflective targets (no stickers, c'mon guys, all of us are suckers for stickers!). Manual is on the website and another copy was emailed with the note "no paper manual included. Applied Ballistics is in the process of transitioning to the new AB Quantum app, which will soon simplify the control of all your devices. Since this change is happening soon, we’ve provided a virtual manual instead." I have no idea what this transition will look like for Fire4000 users.

Key Features directly from Tango with a few of my own notes:​

We develop our own app (AB Synapse - BOSS) and ally with Applied Ballistic. There are different models of software applications. Search for AB Synapse – Boss or BOSS on both Apple iOS and Android, Google Play.
1. FIRE4000 UltraLite (For Hunting)
2. FIRE4000 Sportsman (For Sport Training)
3. FIRE4000 Elite (For Long Professional Shooting)- I assume this is what we got with lower models coming out in the future?

OLED Display
The built-in laser rangefinder can quickly measure the target distance and angle, displaying the results on the OLED screen. Additionally, there is a setting for adjusting the screen brightness. The display is amazingly crisp, 3 brightness settings, it shows all relevant information as far as I can tell so far. if I had to complain about something. I could use a NV friendly brightness setting on the low end.

Vertical and Horizontal Screen
There are settings for both Vertical and Horizontal screens, available on both the left and right sides. To adjust the screen direction, long press for 2 seconds to cycle through the 1-2-3 options. This function works as advertised and is obviously useful for horizontal vs vertical mounting.

Invisible Laser and Visible Laser
The invisible laser, Class 1 with a wavelength of 905nm, is used for measuring distances up to 4000 yards.
The visible laser, Class 2 with a wavelength of 635nm, is utilized for zeroing in on targets and measuring distances up to 100 yards.

Battery Performance
Battery Model : CR123A 3V
Installation : Battery "+" facing inward, "-" facing outward.

Weight is listed at 420g which is 14.8 oz, I weighed this thing at 15.7 oz including the activation cable, so they weren't lying and this thing is a Chooonk. Not that it's current main competitor Vortex is any lighter at 16oz. This area should be the main area of improvement if there's ever a V2 of this. MARS is 1/2 the weight (and 7x the price, I know) but the technology is there nowadays, and I don't see any backcountry hunters packing an extra pound when handheld RFs are in the 6-8 oz range nowadays.
Dimensions listed are 111x75x47mm, which is 4.37x2.95x1.85in. The width is really 2.5in if you don't measure the battery cap and the height is closer to 1.5in from top of the rail.

Performance:

Popped a new CR123 in and powered on unit. Manual is straighforward, setting this thing up is very intuitive including the BOSS app and took 2-3 minutes. I have a S&B US waiting on a mount, so I took the chance to mount it on some spare NF rings and threw the Fire4000 on top. You could follow the zeroing instructions at 100yds, but at dusk, the red laser is visible out to a good distance so I just parallel zero'd at roughly 1000yds in the near darkness.

While we are talking about zeroing, the red laser activation button can be hard to activate/deactivate (this is by design to prevent NDs). The elevation/windage adjustments have no clicks to them, it just feels like you are turning against about 2-3 in/lbs of resistance. This doesn't bother me as I never understood everyone's obsession with tactile clicks and somehoe judging optic's tracking ability by how the clicks "feel" or "sound". Unless we are talking about TT clicks, but that is more of an art to me than a necessity. I'm probably starting an argument here so I digress... Looking through the optic, you can clearly see the laser moving the direction you're moving the flathead screwdriver, no biggie, gets the job done.

My vis seems fairly well slaved to the RF laser, I didn't get ranges off target (or inversely no range while on target) until I got out to ~2000 yards and even then it was only .1mil in the horizontal direction.

There are 2 AB modes on the unit, External and Internal.
External is straight forward, pair with a kestrel via BT and go. Connection is fast and automatic once you initially pair them. I have had those two units synced for about 30 min total so far on about 5 occasions and haven't dropped connection once. Kestrel gets the range from the Tango, does it's thing and spits the solution back out to the Tango under 0.5 sec. One great thing I was excited about is you can build your target card on the Kestrel by ranging with the FIRE4000, great.

The internal mode is a little different story and I hope I get some feedback from others so I can update. You use the BOSS app to set up the rifle profile (is the Quantum making it easy to transfer profiles from device to device?! because I'm about tired of making the same AB profiles across the ecosystem evertyime I pick up a new device...). This is where I am seeing some discrepancies, when the BOSS is connected to the FIRE4000, I seem to get correct elevation adjustments that match my Kestrel (within reason, some of the atmospheric and DOF conditions were off in below pic resulting in a small discrepancy).

However, once I go to airplane mode on my phone and let the device do 100% of the internal calculations, I get results that are... well let's say not exactly jiving with the Kestrel... EDIT 2/3/25: no longer an issue here after talking to customer service some more. Let me explain how this works and what most likely happened here. The Fire4000 gets the gun profile, atmospheric info, DOF and angle of fire from the phone app when they’re connected. Once you disconnect from the phone app and rely solely on the Fire4000 unit, it still uses the gun profile, DOF and atmospheric info that it had last received from the app. However since there’s a built in inclometer, it updates the angle of fire autonomously. That being said, what most likely had happened is I fudged the angle on the phone, then when I disconnected from the phone app and took a new range, the Fire4000 adjusted to the correct angle and spit out a different solution as a result. I confirmed tonight that I can’t replicate the issue, so as of right now, the standalone mode is gtg as far as I’m concerned. One other thing I noticed is that when you’re in AB external and connected to the Kestrel, simply switching to AB internal doesn’t automatically pick up the BOSS app on the phone. It’s like the kestrel is keeping the device locked in. I have to disconnect the kestrel first before the AB internal picks up the phone app.




Ranged .2mil targets no problem out do 1000yds, all I have available past that are buildings, a water tower and stadium lights, it hit all those no problem to 2000yds first time everytime for me.

Random facts and thoughts:

Ranges compared to my Sig8k came back 3-5yds long on the FIRE4000 consistently at all distances, whether it was 100yds or 2000yds. Not big enough discrepancy to be able to verify with a GPS, so I'm calling it good enough for gov't work.

Vibration when acquiring a target is a feature I thought would get turned off immediately, will have to see how it affects battery life but as of right now it's actually a useful tool I will keep enabled.

Tango Innovations is a company I know nothing about, according to their contact, they appear California based, customer service communication has been ok so far.

Unit is made in China (ewww) according to the box.



Mount is a spring loaded crossbolt design with 2 screws, no torque spec included so I guestimated and sent it.. Update from Tango: 40-45 in/lbs recommended for the mount.


Powered by a single cr123 battery positioned in the correct perpendicular orientation.

Confirmed some load data and fired roughly 50 rnds of 6.5cr out of LMT MWS today, holding zero so far



Activation switch could have been lot smaller, if not even just just more low profile, but not a deal breaker compared to a Raptar switch etc..

Distance and internal solution return is lightning fast, like .2-.3 sec is my guess.

Buttonology on top of the unit is well thought out, with most buttons providing a function with a short click and then some sort of a mode change with a 2 sec hold. GTG there, simple and effective.

Will have to update later on how this gets along with my PVS26, didn't get a chance to go out for night shenanigans this weekend.


I'm sure I missed a ton, fire away Hiders, let me know what else there is to touch on...

Cool test done by [B]MinistryOfTruth[/B] on 2/3/25

28F Freezer Test (MinistryofTruth)​

Unit did not form any internal condensation when frozen to 28F for 2 hours. Was taken outside and used up against Impact4000.​

​

Tango displayed typical low battery warning with CR123, but not with 3.7V rechargeable.​

​

Scanning and other functionality worked excellently. Impact 4000 display was practically inop under same conditions. No display oddities were observed on the Tango.​

​

The Tango is a vfd so a picture of it is worthless.​

@carbonbased was kind enough to put together a list of pros/cons between this and the Vortex unit:

Impact 4000 (Vortex)​

Cons

• Battery life in cold weather with off-the-shelf batteries is very poor (special battery helps, but not sure how much)
• Indication for battery failure is immediatelybefore unit shuts down (not helpful)
• LCD screen is sluggish in the cold
• Big boi, a far bit larger
• A little heavier
• Has own ballistic software, can’t true the ballistic curve at multiple distances simultaneously
• Laser for ranging is different than visible laser used for zeroing. So, must skyline confirm zero with poles, edge of buildings, etc.
• $300-$600 more expensive. $1700 currently at Eurooptic with VX15 coupon; $2000 retail.
• Bluetooth remote
• Too bright at night
• ~1/2sec slower for ranging @ ~600yds
• No haptic feedback

Pros

• Amazing warranty
• Onboard inclinometer

Neutrals/Unknowns/Unclear

• Has onboard environmental sensors* (but these might get messed up by the sun beating down, or shooting from a warm space into the cold, etc)
• Has a compass built-in**
• Made in Taiwan (a pro to me, but maybe not to others)
• Poly exterior
• Workflow, building profiles, profile management, tethering limitations, Kestrel connectivity ease of use, etc

Fire4000 (Tango Innovations)​

Cons

• Can’t read the screen with polarized sunglasses (not sure how big a deal this is)
• Only a 3yr warranty
• Remote cable doesn’t have a right-angle option
• Too bright at night
• Too easy to switch between meters & yds
• “When updating environmental measurements using the phone and not having phone perfectly at 0° (the) incline reading gets wonky.” from @boomslang (link)

Pros

• AB onboard, can true ballistics at multi-distances simultaneously
• A fair bit smaller
• A little lighter
• ~1/2 sec faster ranging @ ~600yds
• Cheaper, $1400
• Wired remote
• Haptic feedback
• OLED screen (apparently not sluggish in the cold, users confirm please)
• Onboard inclinometer

Neutrals/Unknowns/Unclear

• Cold weather performance still up in the air (28°F test isn’t actually cold, in my book. It’s warm.)
• Made in China (a neg to me, but maybe not to others)
• No environmentals onboard*, but as mentioned it does measure shooting angle for correct ballistic solution
• No compass**
• Metal exterior
• Workflow, building profiles, profile management, tethering limitations, Kestrel connectivity ease of use, etc
• Zeroing ease (is viz laser same as ranging laser?)

========
Notes:
*why the Fire4000 not having onboard environments is probably no big deal.

**ditto with the Fire4000‘s lack of a compass: see here

We have been getting some awesome rifles built off the Tikka T3X action. This one is chambered in 6.5 PRC with a 3 tone Cerakote job on the stock with Snipers Gray, Black, and Raw Carbon. with a 20" Proof carbon fiber barrel. Click this link to check out the 6.5 PRC Tikka T3X Rifle. If you have any questions Please feel free to reach out at 435-462-1607 or email us at [email protected].

So I decided to play with a Springfield 2020 RF to see if they are really as bad as they say they are......Mine sucked bad. Shot almost 5" at 100 yards.

So I tried to see what I could do to make it better. There was a thread here asking about barrel and I decided not to clutter that thread up and just start a separate one.

I did end up getting mine to shoot fairly well.

Is the Shooter App that bad?

I will preface that I'm comparing the Shooter App vs AB Quantum Free...for now

600 yards 6.5CM
Shooter app said 5.3MIL up, which is what I used.
It started pouring rain, we were prone out in the elements, and range closed due to Tornado warning, so couldn't experiment/troubleshoot
I came home confused and downloaded AB Quantum.
AB said 3.8MIL
That's a HUGE difference.
Same rifle and bullet data input

Shooter app I had plugged in G7 from factory box @ .311 BC
AB is saying 3.06 BC, so I Used that for AB app

I'm obviously inclined to believe AB since Shooter led me WAY too high for MIL adjustment, but AB seemed just a tad low in my head.
1.5MIL @ 600 yards would be below +/-32" and therefore possibly off the 36" target paper?

Backstory,
Zero'd rifle after scope & chassis install, and chrono'd ammo @ 100 yards, w/ Garmin.
Attempted 1000 yard and was WAY high, not even on paper.
Went back to 100 yard range and reworked zero, minimal change. It was windier that day but shouldn't affect vertical.
2 weeks later shot @ 600-yards, and again, shot very high, but at least on MR1-C paper, about 15-18" high, didn't get a true measurement. Can post a pic later Tight enough group that I don't doubt torque values, but will re-verify.
We were at 40 feet elevation @ Marine Corp Base Quantico.
74*F/70%RH by Accuweather app. Winds negligible. Yes...I'd like a Kestrel for true readings. lol.

Ammo:
Federal Gold Medal Match Berger Hybrid Target 140gr
Chrono'd Velocity 1760fps
SD by Garmin as 7, not too shabby for Factory ammo

Rifle Data:
New build Impact 737R, Stuteville 26" CRB 6.5CM 7.7-twist Comp profile. About 140 rounds total through the barrel so far.
MDT ACC Premier Chassis
Arken 7-35x scope
Sight leveled in MDT rings w/ Arrow products scope leveling tool, and verified w/ SG Pulse electronic level.
Height of scope over bore inputted as 1.5" but definitely need to go re-verify as I know this can cause a multitude of issues

Thought I would share that US Army Sniper Ed Eaton is selling a nice rifle. He was featured on Sniper Deadliest Missions, fwd to 1hr 12min

Nominated for the Medal of Honor for action in Nam.

Used PVA Osprey prefit in 6mm BR for ARC Nucleus/Archimedes - 26", 1:7.5 twist, M24 contour, 5/8x24 threads. Per original owner, 385 rounds fired & shot under 1/2" MOA with 30.2gr (Varget or XBR). Only reason I decided not to keep is that I picked up a 6 br barrel for my AI and I don't need two.


Had this listed before and didn't have any serious offers, so I decided to see how it shoots. Shot sighters at 50 and 100, and then two 5 shot groups with Lapua 105 gn factory ammo. I screwed up the last shot on the first group becausethat's what I do, but the second turned out like I'd expect one of Josh's barrels to shoot. 401 rounds on the barrel as of today.

Used for less than 100 rounds. No bolt release, right side safety.

To get impacts beyond 600 yards, I’m having to change my bc from .292 to .280 AND change MV from a twice verified (two garmins running side by side) 2770 to 2750. On the Hornady app, this equates to 2750 and a AFF of 1.10. If I don’t change the muzzle velocity, there is no allowable AFF large enough to give me true results. To clarify, if I put in the largest allowable AFF and start lowering MV, 2750 is the first speed at which the calculated dope matches reality after conventional rounding. The curve predicted by AB matches at .280/2750. If I put the verified MV (2770) in to AB, i have to go to a BC of .272 to get hits.

This is verified at both 1800 ft and 70* and 7000 ft and 40* on small enough targets that I’m confident it’s not just bad shooting/spotting.

Berger 109 LRHT, 7.5 twist. 1000 rounds on the barrel/brake combo. 30 rounds over the garmin shows an SD of 8 and an ES of 34 and the barrel shot two back to back cloverleaf groups (sub 1/2”).

Anyone have any ideas why I’m seeing such incredible inefficiency downrange. Something about the bullets? A barrel problem causing a change to external ballistics? I’ve never seen such a huge truing solution required.

Matchmaster seating die is destroying every 3rd or 4th 143eldx.

New lapua 65prc brass. Run over expander mandrel (262) for uniformity.

Load isn't compressed and I'm getting what appears to be actual extrusion of the bullet into the stem. I know the vlds shape are prone to scoring with standard stems, but can seem to find a vld Stem for this die.

Has anyone seen anything like this before??? How did you solve it?

I bought my first accu-tac ever ..it's a br4. Based on various reviews of being rock solid and stable , I decided to pick it up.

Seems nice but my concern is there is alittle front to back wiggle on the legs. Is this normal? My Harris is has no play in it when it's at the 90deg position so I want to make sure I didn't get a defective product ..
Thanks

So just picked up a DNT hydra the 640 unit. Just curious what the overall impression is on the unit. The one comparison I’ve seen with the RH25 it was impressively similar for half the cost. I’m coming from a pulsar XQ38 from 4 years ago or so i let go so im curious if its going to be a tremendous jump in quality. I’m gonna throw it on the mk12 mod H

I believe this account has been hacked due to the PM’s I received with typical scammer lingo. Yes I did report it to the mods just want others to be aware.

Gforce 1911. What front sight is this? I need the same one, but a lot taller, and green. I like that it is contoured to the slide and has a set screw.

Looking to move to Bluffton SC and wondering if there’s any long ranges close to 1000yds. Also interested in PRS matches out there!

Hello guys,
finding "the right bullet" for a new rifle.

I´m buying 3 or 4 bullets which fullfill my needs, and then I´m loading and testing them side by side.
That means I shoot 4-round groups with every bullet, one after the other, waiting around 1 minute to let the barrel cool down a bit after every shot.

Do you think that "mixing" the bullets is a bad thing, because of the different materials in the bullet jackets?
Will it cause worse precision and would it be better, to test only one bullet in a row, when finished clean the barrel, and than testing the next bullet?

Does anyone have a way to get in touch with annealeez? I'm having a problem with their annealer but can't find a phone number. I tried contacting them through their website, but an error comes up.
