Bear Creek Arsenal 10mm

I’ve always wanted a PCC in 10mm! I would be interested as well. It would compliment my Sig Legion in the mighty 10! Just ignore these morons who think it’s an AR hahaha! Idiots are gonna idiot.

I have wanted one as well, but the blowback design doesn't work for me as I would only want to use +p ammo or full power reloads. Most commercial 10mm ammo is very anemic, almost 40cal perf

I’ve shot lots of 10mm Buffalo bore 180gr (1,350fps/M.E. 728 ft. lbs) and 220 grain (1,200 fps/ME 703 ft. lbs.) out the TNW ASR, seams to shoot great what’s the concern with blow back?

Surprisingly, the blazer brass 180 TC (FC? Don't have a box in front of me) runs 1250fps thru my chrono (6" glock, only 25fps slower thru a 5' 1911) is as hot as any reloads that I have been able to do up using 231 or hs-6 (could we get some 800x again, please), and good accuracy, so at least there is an affordable, available +p-ish load out there. Haven't been able to find Buffbore stuff out west for a while (despite the factor only being a few hours away).

With 10mm the loads are made for a 4-7" barrel, with handloads and a carbine barrel you can switch to a slower powder to get a bit more burn for the entire barrel length. I was able to get some surprising velocities from 9mm/156grn using a m1-9, without pressure signs, I would suspect 1500-1600fps to be within reach with the right powder in 10mm.

You can already get 10mm from kriss and tnw (the aero) if either of those tickle your fancy.
 
"Bear Creek Arsenal has just launched their new 10mm and .45ACP rifles and pistols as an extension to their side-charging blowback action, which is an evolution of the AR-15 pattern"

Well the RCMP wont find this online and will not determine variant for sure


If you want to look into why members here are so confident it wont pass then take a look at Murray Smith's Testimony and Affidavit in the court case re: 2020 OIC and look at anything involving variant.

They approach it as a may-issue, not shall-issue. They look to disallow

How many is a lot?

The blow back 10mm rifles on the market are made to function with regular ammo, not +p+ or reloads. You can confirm this by contacting the manufacturer.

If it was a gas gun then it could be regulated accordingly with an adjustable gas block.

The extra force from +p+ ammo or reloads on a blowback design is going to lead to parts failure

Stop the BS about reload.
Reload to the same power level will be fine as much than any ‘regular ‘10 mm ammo if there is such a thing.
Any 10mm load in reloading manual will be ‘regular’ load. If the gun can’t take that, the manufacturer should go back to the drawing board.

Many Colt Delta Elite 10mm (original batch) just had their feelings hurt (perhaps the tears will hide the cracked frames).

Wouldn't a stiffer spring handle these overpowered ++++PPPPPPPPPP+ loads that a select few are worried about?
Glock says don't use reloads in my g40s. 300 blazers, 100 S+B, 150 federals (f u with your tight primer pockets, federal) and 5k+ reloads of the above brass, everything is working fine. Reloads are as spicy as you make them, mild titegroup cycles fine, full hs-6 slams the slide hard against the back of the frame (i swap the springs in my cz75 when shooting hot stuff, tough to find for the g40). This isn't an insurmountable obstacle.

These discussions appeal to my autism.

I am in, if someone can make or bring in a NR 10mm.

Its called the tnw asr (although we often refer to it as an aero. No idea why). Last i checked tillsonburg had the best price in canada (right at $1k, free shipping). Takes glock mags (the best mags, cuz they are cheap as chips). Stop reinventing the wheel.
 
No more than the Thureon, FX, JR or other AR wannabes. The receiver is new and proprietary, as I said. If it ends up prohib that's one thing. Pretending you are psychic and declaring it so is another. Literally nobody asked for the opinion of either of you. I was asking and waiting for a response from someone who matters.

Why do it in a public forum?

No, in a straight blowback action it's the reciprocating mass (bolt and buffer) that controls the timing and speed of the action opening. The spring weight is insignificant on this front.

The spring rate does speed up how fast the action closes, though. So if you put a heavier action spring in, you will increase the wear from the action closing. And you will sometimes need heavier magazine springs to keep up.

Most manufacturers say don't use reloads, it's mostly just a liability thing.

I learned something today, time to lock this thread down (don't want any more of that going on).

Lets be honest, they prohibbed my mossberg 715t because the plastic wrap around shell kinda looks ar15-ish. Until there is a change of direction with firearms regulations in this country, you would have a tough time getting a blunderbuss approved...

I didn't realize the JR Carbine takes AR uppers.

This BCA AR-15 complete .10MM rifle has a 16" Government barrel with a parkerized finish, and features a 1:16 twist rate, with a blowback system. It includes a 15" MLOK rail, an M4 flat-top billet upper receiver, a BCA bolt carrier group, a flash hider, and a side charging (Gen 2) handle (patent pending), and the BCA mil-spec BC-10mm lower. Uses Glock style magazines.

Considering AR uppers are prohib I don't think it requires psychic powers to figure this one out.
 
It has standard pin arrangement and would likely be declared prohib. Fair enough. The semantics in the literature have been addressed, I am glad at least some possess the reading comprehension skills to see why I even bothered to ask. Seems like all they did was make an AR lower with a different magwell...
 
Also comes in boring .45 ACP.

Ah! I think I've been Triggered!
Boring .45?!
