.22 Magnum (WMR) Complete Guide: Ballistics, Applications, & More
The 22 WMR complete upper assembly used to come with one 10-round magazine and the receiver engraved ".22 WMR". I ordered mine with a 20" SS barrel in late 2023 plus two 10-round magazines. The upper and mags arrived quickly but no caliber engraving. An email said it was a discontinued feature. Too...

Barrel Twist Rate Guide: Why It Is Important
I was interested in a bolt action upper assembly in 400 Legend. The Bear Creek Arsenal barrel is shown as 1:8" while every report and article read about the cartridge have rifles with 1:16" twist. I'll put this off pending more information.

6.5 Grendel vs. 300 Blackout: Ballistics, Applications, Ammo, & More
I have both BCA uppers. The 300aac is fantastic on hogs and deer at 100 and possibly 150yds would be my max on that round. The Grendel is sweet also and I wouldnt hesitate to use it at 250 on deer or hogs. Both are very pleasant with almost no noticable recoil. Very fun rds to shoot out of an AR...

10mm vs 45 ACP: Which One Is Right For You?
Pistol Carbine shooting is a lot cheaper. Wish they had the whole lineup of carbines I would have more than just their 9mm and I have all three they sale. Thought I saw them have them now they don't. So sad.

Does the buffer tube on a bolt action pistol, need the buffer weight and spring or just the tube and brace? Thanks

Hi BCA, could you make a stainless finish, non threaded G31 .357 Sig barrel? That would obviously be the G17/22 length barrel. Thanks

Purchased the BC-10 .308. Ordered bolt action by mistake but was impressed with it so I ordered the BC-10 .308 complete upper swapped it out works flawlessly except I did have to get a buffer and spring but really impressed. Impressed enough that I’m ordering the BC-15 .223 Wylde. Just waiting for more discount codes. Lol

Any chance you guys could do something in 300 Hamr and/or 5.7 x28?

Bca has been amazing but everytime I have money for the thing I want it’s always out of stock for a long time. I would like to see the stock be available more often other than that no complaints.

Just received my 20" 556 AR15. Can wait to try it out. Any chance we'll get some 24" heavy barrel 308 or 6.5 in the future?

I am a big fan of BCA. There is a round that is fantastic and there are a few semi auto rifles in it. The 17 Winchester super mag is a fantastic round. I hope BCA will come up with a full upper assembly for this round.
