Rifle Scopes March 5-42 Gen 2 PRS Edition

Wow, this thread has taken some twists and turns. A few comments after reading through some...

do you guys cry about Richard from CS Tactical when he post to sell a zco… no you don’t.
Actually, some people do cry about Richard, they just do so behind closed doors... :sneaky:

Are the Gen 1 and Gen 2 versions the same glass wise? Are the differences between Gen 1 and Gen 2 reticle and turret/mechanical differences only?
I know there have been some responses to this already but speaking from personal experience, the Gen 1 had some optical distortion from about 60-70% out from center to the edge of the periphery. My eyes are very sensitive to distorted or blurry periphery in any scope design (one of the worst I had seen was the NF NX8 2.5-20 when it was first released; however, to Nightforce's credit they resolved that in later manufacture and now the "newer" NX8 2.5-20's are very impressive optically). I was thrilled with the March 5-42x56 Gen 2 version as it corrected this optical distortion from Gen 1 quite well, meaning the image sharpness is very clean from edge to edge. I have only had a pre-production version of the Gen 2 5-42 but based on my experience I am not surprised that so many are really liking this scope as I think for PRS style of shooting (where 98% of the time you are between 12x - 20x magnification) this scope is absolutely stunning, in fact, in this mag range I liked it better than all my other alpha scopes I was testing at the time including the TT 7-35 and I was very hard pressed to find any distinct advantage the TT provided (again within this mag range, where the TT excelled was above 25x).

It's interesting, Kahles kind of shook things up with their new K540i with ultra wide FOV; however, March had already been doing this for a number of years and I've been trying to enlighten the community on how advantageous wider FOV can be. Once Swaro's patent ends, presumably around spring/summer next year, I think we will begin to see more manufacturers take advantage of using wider FOV eyepieces in their designs.

Hornady is good shit.

It’s not though. If you happen to get a good lot then yes it will be good ammo but never great or exceptional. Their problem is that their lot to lot consistency is absolutely horrible and it’s been that way since before Covid and powder availability and every other possible excuse. I have experienced this over and over again buying their ammo because I continue to use it even though I would not overall generalize their products as “good shit”. I feel like “usually acceptable” would be more accurate.

Im looking for a similar type of optic for a 6 arc gas gun build…what did you end up going with?

Here’s what I’m currently considering, strongly leaning towards Midas TAC Gen2 UHD 5-30x56:

MPVO: Bushnell Match Pro ED 3-18X50 (# MP31850DMI) (28oz) ($580), Ares BTR GEN3 HD 2.5-15x50 (27oz) ($692) , US Optics 3-18x50mm TXH EMCR (35oz) (too heavy) ($620), Burris XTR III 3.3-18x50mm (# 201204) (30oz) ($964) (don't like the reticle), Element Titan 3-18x50 (34oz) (too heavy) ($780)

HPVO: Athlon Midas TAC Gen2 UHD 5-30×56 (30oz) ($585), Vortex Viper HD FFP (VMR-4) 5-25x50 (25oz) ($850), Athlon Midas TAC Gen2 HD 6-24X50 (26oz) ($540), Athlon Helos BTR GEN2 4-20×50 (27oz) ($540), Arken EPL-4 6-24x50 (24oz) ($350)
If you are considering an HPVO, Midway currently has the PST II 5-25 on sale for 600 bucks. Not the best reticle, but it is such a damn good scope, it is hard to pass up.

AB Elite devices are not synchronizing

I was having similar intermittent and weird connection issues with my Kestrel 5700 Elite a few years ago. After troubleshooting online and over the phone with Kestrel support, they had me send it in and they determined the Bluetooth was defective. Then they wanted me to pay full price for a new one. I gently declined and eventually after some back and forth, they replaced it free of charge. Maybe reach out to Kestrel directly.

It is actually pretty complex to get something like this working on a phone. It's not as easy as a day of coding.
Coming from the IT world, I fully understand it's not a super easy process. But as an end user, having the same capabilities on the phone as exists on the Garmin is highly desirable. Having all of the devices at once is a super nice to have, but having at the very least the weather/kestrel/calypso along with whatever range finder connected at the same time is almost mandatory.

US optics FDN

There are other threads on the topic, with a couple of loud people who like to dog on the brand based on experiences two business iterations ago with products that were discontinued nearly a decade ago or more.

We don't need to open another thread where I duke it out with the same person on the same issues. Here's some links to existing threads.



I love my FDN 25x.

That is exactly how it SHOULD work. I mean you can connect an LRF and a Kestrel to a Garmin device at the same time. There is literally zero reason you shouldn’t be able to do the same thing on a phone.

As I said, I love AB Q, but there are a number of very simple things that you can’t do. Quick example is you can’t rename a device in the app. But since you can only have one freaking thing connected at once, I guess it ultimately doesn’t matter.

Already tried it and i must say its perfect. Only minor gripe is with one accidental “swipe”. you can delete all custom groups or targets and reverts to default. This is not cool as sometimes during matches one forgets to shut down screen on phone and things happen.
They should only delete if you hit the trash can button.
