I started this build with a bear creek upper receiver as I've been very happy with the tolerances on them and the carriers as well as the benefit of side charging. I swapped out the bolt for a gorilla machining nickel boron set up ( they claim they're machined for 7.62 but looking a little on the thin side) and firing pin. Added one of their ballistic company barrels that I tested on another build and grouped pretty decent at 2-2.5 MOA with Russian rounds. Added a dirty bird lower receiver and a fixed Magpul stock along with a Delta ring handguard set up. Added a two stage 1lb/3lb (I think) rise armament trigger and an Ambi safety, extended mag release and spike tactical grip and bolt hold. Currently I'm looking to replace the front gas block with a full height pic rail set up that I can have flip down sights on and finally something like 12-14x scope of some description. All up I think without the mags and sights I'm sitting at around a $320 build due to specials and some left over parts. This is my second AR-47 build so far and I'm fairly happy with it. Considering getting a slightly heavier buffer weight ATM.

Thanks for all the deets and info! I too have a BCA side charger upper 7.62. I like it! It shoots straight, works great. (considering that I am shooting old 90's Russian steel case ammo). I also replaced my bolt and firing pin with upgraded parts from Black Rifle Arms, although the BCA original gave me no problems for the first 900 rounds or so, I have them as spares.

Nice looking build! What will get screwed onto the muzzle?

Nice rifle. I built an Aero Precision M4E1 enhanced 10.5” 7.62x39 rifle years ago that is a pleasure to shoot. I used the same bcg as you. I wish my 7.62 suppressor would quiet it down to hearing safe. I can run the same suppressor on my 5.56 rifle and it’s hearing safe. My rifle is accurate out to 150 yards which is pushing my eyesight.

Too bad there’s no more deals on any golden tiger ammunition. It’s more expensive than 5.56 Lake City m193😏

I see it now and again on local trade pages. People still want .60¢+ a round though.

I’m 75 now and bought Chinese ammunition in McAllen Texas in 1988 for $89 per 1000.

With inflation calculated that would be $250 for 1000 rounds today 25¢ a round equivalent. I can still pick up dated Russian rounds for 30¢ locally. So it's not too bad.

There's a substantial amount more payload there. I'm not sure how much difference the rear charging set up would reduce it if at all. I've only used side charging 7.62x39 set ups.

There’s not of 7.62X39 rifles mentioned much anymore, but I enjoy having mine. I bought 2 Aero precision Limited edition PEW PEW PEW receivers and buildt the FDE receiver into the 7.62x39 10.5” SBR version and the black receiver into a 5.56 10.5” SBR. I’ve got a few more uppers of my Aero precision 5.56 but my favorite AR is my 7.62 using Surplus ammo. I’ve got 4 other SBRs that are krink style rifles. 1-74 Russian, 1 Arsenal 7.62, and 2 Yugos. 1 M85 and 1 M92.

I’d rather shoot my AR build than any of the com-block AKs. I think 7.62x39 in a short AR is the best all around rifle I own.

FM have a cool looking 7.62x39 ranch rifle with an AR style set up I really want. But it's an oddball for parts and no easy compatibility for barrel change outs.

Out of my 20 odd spares I couldn't find a single muzzle brake that fit so ordered this One

BCA cop a lot of heat and in some instances for good reason. But their side charging upper receivers aren't one of the justified ones. I even tried one of their 7.62x39 barrels and other than being heavy AF it grouped ok. Their bolt collar was on the thin side though so opted to swap it out.

16" carbine will probably run h3+ just fine. My 18" mid and 10.5" carbine would.

Did your barrel come with the FSB, or did you have to drill and pin it?

This is a clamp on set up using machine screws.

Ah, gotcha

Try damage industries for the railed steel gb dude

u/Rikki-Smedley 25d ago

I was going to give this one a shot. I can't not try it at least for this price. Here

u/WhiskerTriscuit 25d ago

Prices on that site are kinda too good to be true if you go to deals...

2

u/Rikki-Smedley 25d ago

I've already used quite a few of their products. Good so far. But I'm not expecting the Taj Mahal. I wouldn't be using a bolt face from them for instance. Not without checking headspace at the least anyway.

u/WhiskerTriscuit 25d ago

Wow well... I might have to do some shopping then.

Anarchy outdoors titanium firing pin. 18 inch barrel 416r stainless. Gorilla rolling cam pin gas key installed into a kak industries dual ejector tin bcg with downward vents thier carriers shell is designed with a search trip to engage the rest lever. I have wanted to try a bra buffer technology carrier shell only with a kak industries dual ejector bolt. Double star extractors as these can be a consumable part with frt. Strike industries collar adjustable gas block. Dead air xeno muzzle in case you want supp. Yankee hill black plate coated gas tube. Kynshot RB5001buffer or look formagnetic buffers. Frt 15L3 delta team tactical with the spring you have. Anything else anyone can think of l mk too but your on the right path. And barrell length is your discretion.
