BCA Bolt Action AR15

[farmbif]

I guess if you live where you cant have or hunt with a semi auto and there are exacting specifications of what the cartridge measures and looks like if you want to hunt then those are built for you.
But wolf, you only live once. go for the gusto if that thing has your full attention. but, you live in Mississippi. you could just get an AR in one of those calibers and a few big magazines and go for it. unless those bolt actions are all that much more accurate or something.
like dverna I have a couple, few AR's. 556,300 blackout, 6.8spc and I'm thinking seriously of getting a 300Hamr barrel and building another upper or throwing away the blackout.
so I sure do know what its like to see something, read about it, look at all the stuff, convince myself I need to do this, ect, ect, ect.

WOW! That is about the perfect setup that I didn't even know that I NEEDED!!!

Even though they have all the parts (from other AR uppers they make and sell), BCA said No to putting together a bolt action upper with a 10.5” bbl 5.56 for me.

I'm betting it's due to the lack of primary extraction. It may not be as big of an issue with lower powered subsonic loads but it will be an issue for something like 5.56. I had a rem 700 in 223 with bad bolt handle timing causing it to not have primary extraction and it was a pain in the ass. After firing the gun, you would have to wiggle the bolt handle or slap it toward the rear to pull the spent brass from the chamber. I would expect this BCA upper to be the same way with no action ramp to bolt for a camming surface.

Just got back from my first range trip with my BCA bolt action 5.56. Worked like a charm. No issues with extraction or anything else.

Did you shoot any groups?

Yes, my aim today was to get new scope sighted in. I'm no Adolf Topperwein but I did manage a couple of sub MOA 100 yd groups. Just got the upper 3 days ago and used a load I had on hand.....likely will do better with some load development.

Looking forward to developing some castboolit loads.

Personally I hate the big mags , biggest I run is a 20 usually it's just a 10 with 5 in it. Bout all mine are pretty close to my bolt guns

I am right there with you on the big mags Wolfdog91. They just get in the way at the bench.
When I shoot Hogs, I generally get 1 shot and they scatter. A few years back I shot one that took 3 grown men to lift about 15" into the bed of my truck that was backed up to an embankment. That one I popped in the eye with my 450, they all scattered, then a smaller one ran back out in the lane and stood there for about a second and I dropped him too.
Unless the world goes to ****, I don't really have a use for high capacity mags. Most of my AR mags are 5 or 10 rounders.
Thread drift...

Back on the subject:
You said you wanted a 5.56 10.5" bolt action upper?
Buy the 350 complete upper, then swap in a 10.5" 5.56 barrel and hand gaurd with one of the gas port block sleeves. You could put the 350 barrel on the shelf for a latter project, so sell it to pay for the other barrel?

I'm in the process of putting together a couple of 30 AR-15 wildcats on either a shortened .308 Win case or 450 Bushmaster cast shortened and necked down in 30 Rem AR dies.
They will both work with a 450 Bushmaster bolt. So I ordered a complete side charging 450 upper from BCA, and will just swap my barrel on when it's done. It was actually cheaper to buy the complete upper vs buying the upper with BCG, then the hand guard, gas block and gas tube. This way I have a space 450 barrel for later...

Has anyone checked the BCA bolt with a primed case to see if it will pop the primer unless the bolt is closed all the way?
I know someone checked and the hammer would fall, but did it reach the firing pin?
The spring loaded bolt in their carrier, does that rotate the bolt to engage the lugs in the barrel extension? Or does that only happen when the bolt handle is rotated down?
If the bolt is spring loaded forwards, then the firing pin wouldn't be able to reach the primer unless the bolt was all the way forward, but before the bolt handle is turned.
So does the carrier block the fall of the hammer in the forward position? and only let it fall all the way when the handle is rotated?
I don't really need a bolt action AR. Toys are always fun though...
I could see a big market for this in California for people that want an AR-ish rifle.

Any info on if affordable 338 Arc barrels are anywhere? Seems like people had them for a couple of months and everyone is out of stock

I haven't bought one for this exact reason. It would really ruin your day when it happens. The lack of primary extraction also makes me hesitate.

Good pics and lots of them; thanks Wolfdog!
The advantage I see is easy brass retrieval for the exotic cartridges like .400 Legend, .458 Socom, etc.

Looking forward to your range report. I am warming to the idea of this if it works as I am looking at adding a .300 BO.

In the third picture there is some "uck" on the frame between the bolt and the rear on the left side of the action. Is that normal?

Been thinking about getting a .300 BO barrel for one of the uppers or a new upper in .300 BO. Was looking at this bolt option, but the concerns voiced by Lar45 and tangolima make me hesitate. I know nothing about AR's even though I own four in 5.56/.223. Just not "my thing"...old man syndrome.

The .300 BO is not available in the BCA bolt upper. If I get the BCA bolt receiver and add a barrel I am at $300. Might end up with a traditional bolt gun. The Ruger American uses standard AR mags and is about $500.

Just got whatever factory stuff I could . Not much selection round here but it's something, never known PMC to shoot too well in anything honestly but hay.


I'm dropping that low right one in the hornady group. Was obvious that ammo shot better then everything else so I shot two more just to see. Might have been me might have been whatever but 6 out of 7 in a group a bit over and inch... I'll say that's decent odds lol

Well lemme finish moving stuff around. In the house and I can measure this brass and start in that

Thanks Wolf!!

I bet your handloads will do a lot better...IF YOU USE THOSE EVIL JACKETED bullets. LOL

But too shabby for the first groups out of a new barrel.
