Why is there an MG pintle mount on a police Bearcat?

What scenario do they envision needing an armored vehicle with a MG on it?

Asking for a friend....

Cosplaying like they are in iraqistan

Never know when they have to get it on with all those civilians that are criminals that haven’t been caught yet.

Not quite! It’s for an acoustic hailing system called an LRAD, but good guess

I must be mistaken, I thought this was an AI picture thread

 

[MK20]

Not quite!

The LRAD mounts to tripod and CROWS (MG) mounts per their website.

Also, per Bearcats website, it is indeed an MG mount.

According to BearCat, you may need a MK19 for "defensive" police operations. Right....

Before you start making snarky remarks, know your gear. But, I would bet you still won't know how to use half your shit but will feel really good going out and pointing it at people because it makes your pee pee hard.


Back to AIs, hopefully in the hands of responsible citizens.

 

[diggler1833]

<<<<<< Scoffs at the term "responsible citizen". I want to continue to be irresponsible, damnit. That's why I divest my children of their inheritance with my firearm purchases.



And I cosplay by putting my boots on and stepping directly in cow shit before I come home and walk around the kitchen until the wife yells at me.

Interesting term for an acoustical weapon

Slinging mud about cosplay and machine gun mounts on Bearcats (as if they’re only sold to LE agencies), while in a thread where everyone posts pics of personally owned AI rifles. This is the brilliance of the Hide.

I do have a solution for that....

However it's a 3-12 LRTS, the only other decent lower magnification FFP scope on the market is the Mark 4hd 2.5-10, and I'm not quite ready to stoop to that level.

 

[beetroot]

Again, it isn't just about the bullet weight, but the bullet length as well that matters.

Plenty of folks ran the M40, M40A1, M40A3 and M40A5 out past 1000 yards just fine, which has a 1:12 twist barrel, and ran M118LR rounds, essentially Federal GMM SMK 175gr. I did reach out to a sniper instructor peer who has combat experience with the M40 rifles, who confirmed the distance and capability for me.

We also have @FUNCTIONAL with very direct experience running the M40. Sorry to call you out but it's important. Hell I want to share more of that shot data just as a solid reference...

There's no reason why the 1:12 Lothar Walther barrels aren't extremely capable. But, the right round needs to be chosen for it.

And so this circles right back to why I made my original post sharing the shot group: the Sierra 168gr TMK round with it's improved 9° boat tail seems to work best in this barrel, which I've so far tested in 20", and I have no doubt will perform equally well in my 24". My next range day I hope to get 300 round shot groups, and later, 700 round shot groups depending on wind.

I'll share all the images and data I have on this round. For us Yankees, the Federal GMM SMK 168gr & 175gr, and the Federal LE T308T 168gr, seem to be the most effective and cost conscious round to use in these barrels.

I don't have experience with Lapua or Berger rounds in these calibers, so I leave it to others to comment on what else shoots well. I invite it as this data is important for folks like us to have.

And yes, I read every single post in this forum regarding the Arctic Warfare and AT308 looking for ballistic data of factory rounds, and found excruciatingly little.

I hope the attached data helps for context. And I have much more data that shows how the length of Hornady rounds do not stabilize. I also tried the stability factor with a Berger 185gr round without success, but I'd entertain actually shooting it to see how it performs.

So I run the numbers for more projectiles and other barrel twists, I do know that bullet weight isn't really the issue it's length/bearing surface/ogive that all goes into, probably safe to say that high BC bullets need a faster twist.

The outcome is the same as before, other than SMKs (older bullet design, shorter, low BC*) a 1:12 is not a brilliant choice, especially if it's a short barrel. 1:11 is definitely better but still suffers with some of the very heavy/high BC bullets, and a 1:10 is basically good for anything.

It's worth point out that only the Berger Hybrids are actually unstable in the 1:12, everything else on orange is just marginally stable.
The biggest take away from this whole thing is how amazing the newer SMK designs are 169gr/200gr (also the 131gr .25cal, 130gr and 150gr 6.5mm) these things have massively improved BCs over the old SMK design, often have a higher BC than the same weight TMK yet are shorter and likely more forgiving on seating depth.

I know I could've stream lined this table even more, but it is was it is.

Orange is marginal stability 1.0-1.5.
Red is unstable <1.0
Greyed out means fully stable (because the twist above (slower) was 100% stable at all speeds no point running the numbers at a tighter twist).

Well, actually, I had one on mine for a while.

I think it goes without saying if it shoots well who cares what the computer says.
I'm no expert but I believe you are probably just giving up some BC, the bullets are stable enough for accuracy.

I hope my LW 1:12 shoots as well as yours, I plan to run 168gr ELD-Ms rather than the 178s, more stable, a bit faster and similar ballistics (if I get a bit more speed). I'll be shooting 168gr SMKs to start with (factory ammo). I have a few rounds of Hornady match 168gr ELD-M to test out also.

I should add if I haven’t already that this rifle shooting 178 ELDX is a crop damage hunting rifle. So shooting deer inside 600 for majority of its life. I haven’t shot it a bunch further to see how it truly stacks up at distance. I will be grouping some distances near 500 in coming month when I can access my range area. I’ll share more info then. Just testing a couple charge weights of IMR 4064 expanding of previous testing I did

That said I have an 18” 1:10 Bartlein ready to replace it when needed and would buy a 1:10 over a 1:12 any day. This is just what was on the rifle when I bought it

I’ve probably put 800-1000 rounds through this barrel since I bought it. Had over 3,000 rounds when I got it

Couple bore scope pics. Couple rough spots haha

Anything orange (1.5 and lower) I don't consider stable enough to shoot.

 

[Bacarrat]

Man, this conversation is like 15-20 years old. 12 twist will stabilize 190gr and 200gr SMKs.

No one is disputing that.
It's the newer, high BC bullets that are in question, especially in shorter barrels.

 

[mercracing]

I do have a solution for that....

However it's a 3-12 LRTS, the only other decent lower magnification FFP scope on the market is the Mark 4hd 2.5-10, and I'm not quite ready to stoop to that level.

March 1.5-15?

 

[beetroot]

March 1.5-15?

Yeah that is an option, I was keen on a DFP model but the mixed reviews put me off.

I'm going to use the LRTS for a bit (with the 308 barrel) but might end up with an LPVO for hunting use.
I haven't even shot it yet, so will starting shooting before I worry to much about scopes.

That's if the rifle sees much hunting, it weights 14.5lb as pictured...

 

[beetroot]

Last word on barrel twist (at least until I shoot the damn thing) was this comment from Frank Green in another thread, says it all really, given the choice 1:12 twist is leaving a lot on the table.

 

[HKSniper11B]

This is a reason why I have gone down a rabbit hole researching the M40 with @FUNCTIONAL due to the extensive use of 1:12 twist barrel.

That said, I have a former USMC Scout Sniper and current Army B4 Sniper telling me they "... ran [M40s] out to 1000 yards regularly." Using M118LR. And 1000 yards consistent sounds mighty fine in my book.

But Frank is right: 1:12 leaves a lot on the table, and 1:10 get practically everything done, with .308/7.62 precision rounds.

It's interesting that Frank still shoots 308win. One would think barrel wizards shoot exotic calibers all the time. But I'm actually happy to see this, it's validating.

 

[Amber Terrific Makara]

Be well soon! Might be fun to shoot small calibers for a while, practice is practice, doesnt matter which caliber.
View attachment 8647006

This rifle is beautiful

 

[FUNCTIONAL]

Also have to remember what we consider effective and what the military considers effective are very different. I've had my A5 out to 1200 yards hitting targets but the mil i believe says it's effective range is 800 or 900 yards. Similarly I believe they state the 300wm is a 1300 yard gun effective range. We all know the 308 and 300wm can be shot much farther in either cal. The "goal posts" for civilians and mil are different.

I can't remember which thread i got into the discussion but the AMU typically picks the lowest twist needed to stabilize what they plan to shoot. For instance we were discussing 223/556 and they choose 8 twist slinging 77 class bullets rather than the common 7 twist we would all pick. Some of their beliefs are people over twist and they get more long range consistency with less over twist.

My personal opinion? With the selection of bullets and components we have today it doesn't matter. There is a combo you can make work in any common twist. My go to 308 has a 12 twist and is easier to load and shoot than rifles i have in 11.25 and 10 twist. Some even built with the same exact reamer. Even if you don't hand load the variety of factory options is large enough you'll find something that works.

 

[Hondo23]

I can't remember what twist my 16" has but it loves the 169's compared to 175's.

Does anybody have a diagram or a set of instructions on how to adjust the original first, I'll call it aftermarket two stage AI trigger that Tom made for AI? I don't know if that's the same as the AI comp trigger they're putting out now. I've got one in a AIAT I'd like to make a little heavier.

Do you have a picture? I have a few AI triggers from the 80s and 90s with adjustable trigger shoes that could probably be mistaken for aftermarket, but are internally the same as all "regular" AI triggers. Or is yours an older variant of the comp trigger that were designed/sold under the CG, Jackson, or Xtreme brand?

I believe it was the CG Jackson/extreme trigger that probably came out 2019 maybe 2020 that has evolved into the AI competition. it's an AI branded replacement two-stage.

So to come off like a self-sucking dick, I finally took my new-ish factory 6CM barrel and 108gr ELD-M out to true velocity (I'm an old Fudd with an old chronograph).

650 yards. I'll admit now that the first group was a fluke and probably not repeatable. The second group wasn't a slouch either though.

One mag was all I got in after haying, and then it was time for chores. Just came in from setting 2-7/8" drill pipe fence posts in concrete (I do concrete work and bench presses as side jobs ).

26" Bartlein, 1:7.25". Velocity looks like it is going to be ~3,060 since I was still almost 2 inches high at 3.5.

Internally I'm pretty sure they're mostly the same. CG triggers have always been the same internally and I believe it was the guys at the (now-closed) Shooting Shed in the UK that developed the CG design by Robert Chombart to fit AIs. I had a look at all the diagrams I could find online a while ago and it looked like there was no difference in the general design between the two, so you should be fine to use the Competition Trigger adjustment guide, or a generic CG adjustment guide below.

Although I must say, the original AI trigger is probably better for a heavier pull. The only thing really limited on it is the lack of first stage travel. One of my really old triggers actually has first stage travel adjustment as the housing is machined from billet rather than sheet metal, so there is enough meat at the top for an additional screw for first stage travel adjustment. LRI use triggers from Grunig and Elmiger for some of their custom builds, which has remained unchanged for almost a 40 years now and is essentially identical in mechanical design to the AI trigger, except the AI trigger has a fixed fulcrum point and means it generally doesn't work as well with a lighter spring, whereas G&E can go to 100g or less like a 22 match trigger. Both designs stemmed from the same old variant of the Anschutz Match 54 trigger. The Tubb trigger is essentially a copy of the Grunig and Elmiger trigger

how is that round man?

It does well enough. I'd probably do a dasher or GT if I had to do it over again. They just seem easier to load for. My buddy had a 6x47 reamer and I had a bunch of 6.5x47 brass so it was easy to do. I was thinking it would be as easy to setup as my 6.5x47 (my favorite round) but it isn't. Not bad but not 6.5x47 easy.

Sounds like I'm comparing but it holds .45" to .3" nearly constantly.

 

[Shoots 700's]

6 dasher and 6.5x47 are the easiest rounds I have ever loaded for.

Yeah, I'm on 6CM barrel #2. I gave up on the round after I burned the first barrel out in 1,400 rounds (and I shoot slow)...but it is hard not to come back when the midrange ballistics are stinking good. It is like a little magnum (until you get out to real distance).

Oh hey gents. I sold my ASR kit 2 years ago (a dumbass move for sure and not recommended. Don’t try it you’ll be full of regret) and I’m back baby.

[DKN83]

Since i couldnt get the 50cal, some money is left to do some foolish stuff
I have all the rifles i need and prefer to practice a lot.

Right now stumbled across an unfired axmc in sage green.
I have not seen any troubles with those rifles besides the lfp/sfp. Interested in 308/338lm only. Rifle comes with both bolts, mag change kit and barrels.

Biggest concern right now is the fact the model is discontinued. Thinking of how lost i am with finding sidestocks for my aw/awm, i am thinking about what happens if i need support with this one.

The color is great though

I prefer this one over the newer models but well...whats your opinion on the support issue?
What about the trigger, is this a comp trigger?

Any thoughts about good/bad are welcome.
