I said I would never get a 7.62x39 AR15 so I did anyway.

As I've been blathering on here, I was once an exclusive handloader that hadn't bought a box of factory ammo for nearly 10 years. That meant there were times I didn't shoot as much as I would have liked because I didn't want to use up ammo that I had no time to reload. Well that changed late this fall when I bought a mosin nagant. I wasn't planning to shoot it much so I wasn't going to waste time and money getting reloading stuff for it so I just bought a few boxes of brown bear. Well, the mosin really surprised me with how fun it is to shoot and how surprisingly accurate it is with the cheap steel case ammo. It actually has become one of my favorite guns to shoot and I've put quite a few boxes of ammo through it.

That brought me to looking for a 9mm carbine since that's the cheapest center fire ammo you can buy. I got a really good deal on a hi point 9mm in december with the intention of just buying ammo for it locally when available. I really like the hi point but the factory ammo idea did not work out. I found I much prefer my handloaded 9mm to any of the cheap FMJ stuff I can buy, plus 9mm is very cheap and efficient to load.

I have been contemplating getting a rifle of some sort in 7.62x39 for awhile but havn't put any money towards it. I was looking at the ruger American rifle and an NPAP AK. As I recently said in another thread a 7.62x39 AR has never appealed to me due to needing proprietary parts and because the gun just isn't designed to accommodate it. I really really really like my 300 blackout upper for my AR but its a handload only affair for me. I had decided I was going to put away some money for an Npap AK but last week I got a $100 mail in rebate card and so I decided to try getting a barrel for my AR since the investment is significantly less.

To get the ball rolling I ordered this barrel. I got the barrel in yesterday but it was not as advertised. The barrel I got is a bull profile and weighs 37 oz instead of the advertised 32 but I put it on anyway. I canibalized my 300 blackout upper, gas tube, and gas block to put it together.

I needed a new charging handle so I got this to match my laser engraved lower

I have read to expect light primer strikes so I ordered this enhanced firing pin and extra power hammer spring just in case.

I already had a BCA 7.62 bolt. I ordered an extra BCG a month ago to use in my blackout upper and since I had a spare 223 bolt I ordered one with the 7.62x39 bolt since a friend of mine has expressed interest in building one.

Got it together today. I have not gotten the magazines or the enhanced firing pin but I got it out and shot it a bit to tune the gas block. I didn't have any light strikes so far and I found 5.56 Pmags work if you only load 3 rounds at a time in them. Have not tried shooting for accuracy yet. It only took a half turn open on the gas block to reliably cycle so its way over gassed for my buffer.









This is the same knock off Krink brake I had on my blackout. Its a bit heavy but extreamly effective at reducing muzzle blast. I shot it today with and without and it makes a huge difference

I'm liking the fixed stock.

Also, I'm stunned that you were able to find mags on Ebay. I've never ran across any.

There are lots of AR parts on ebay. Ebay has a policy that they allow people to sell gun parts and accessories, but not assault rifle parts due to the difficulty in keeping up with changing state laws. So if you want an AR15 magazine you have to search for "5.56 magazine" not "AR15 magazine". Same goes for handguards, barrels, stocks, gas blocks, lower parts kits, ect. Just search for 5.56 plus whatever part you want. The only thing you won't find is receivers and bolt carrier groups.

I got my free float tube and stock on ebay

Thanks all. I really wish this barrel was lighter but it is what it is, its used now. I am thinking about getting an Ace skeleton stock for it to save some more weight. When I was building this stuff I didn't realize how heavy AR's are.

Need any more mags I may have one or two Stoners from the election era that I need to get rid of. I'll have to look.

That would be good. I will probably just shoot with the 10 rounders but I would like to get a couple more to keep loaded and ready.

Tell me more about the two charging handles on one gun? Is that normal on side charging AR uppers?

Click to expand...

I don't really know. Bear Creek came out with this last summer and they call it a dual charging upper. The old one they also still sell is side charging only. Both are billet uppers.

https://www.bearcreekarsenal.com/up...-upper-receiver-bcg-combo-5-56-223-urbcg-dc15

I actually ordered the old style side upper with a bolt carrier on sale for $120 a month before the dual charging uppers were released and this is what they sent me. The 2nd one I bought as a bare upper on sale for around $120 also. The bolt carrier looks to just be a standard bolt carrier but with no provisions for forward assist and a hole drilled and tapped in the side for the handle. The rear handle is great when you have a brass catcher on it. The only inconvenience with the side charging handle is you have to take the handle off to take the bolt out. That is why I drilled a hole through it, that way I can take it out with the tip of a bullet or my leatherman. In practice I use either handle depending on which one is more convenient to grab. For example if I'm working the bolt to chamber or unchamber a round I use the right side handle. If I'm holding the bolt open to clear a jam or something I use my left hand on the rear handle leaving my right hand free to work. It works out really well and I highly recommend it. Growing up shooting 22's no semi auto feels satisfying without a handle on the side to yank.

I thought AR's were girls guns anyway?

That dual charger upper only has the standard ar charging handle because it is cheaper to include one than redesign the upper receiver. Only have to make one mill cut to a slick side upper before finishing to build these, and since it's a pretty new system it's cheaper to use existing uppers and only have the proprietary bolt carrier. I built an upper like this about three weeks before these came out, and when I saw these I felt pretty good that mine is exactly the same as the commercial upper.

That it not true. The BCA upper is machined from billet, not a forging, so it does in fact add several machining operations compared to there side charging only billet upper. The intent is that if the side charging handle is lost or broken you still have a way to open the bolt without prying on the carrier.

adcoch1 said:

I stand corrected! That isn't the same build sheet I saw last time I went and looked a while ago. Didn't realize they were a billet upper.

That is a good point though, if a guy had a mill you could make a really cheap dual charging upper by just milling a slot in a $40 forged slick side upper and drilling and tapping the bcg for a handle. I just might have to do that if I ever decide I need another upper.

Well there ya go. I've been thinking about building an AR for a good friend of mine. He wants a side charger but it's never in his budget. Family guy.

I got my mags, the enhanced firing pin and and wolf hammer spring yesterday. Was working on my truck and doing firewood so no time to go shoot. Should get out today. The wolf hammer spring will be a last resort, I popped it in yesterday and as I suspected it increases the trigger pull about 2 lbs so that's a no go. The C products 10 rnd mags appear to cycle smoothly working the action by hand. Anybody know where to get a polymer 10-20 rnd 7.62x39 mag? I tend to like polymer mags better since metal is unfriendly to handle at 20 below zero .
