Is it possible to make a reliable 762 x 39 AR?

Since posting, I’ve bought a 16” PSA KS47 and have a Vortex Viper 1-4 zeroed it at 35 yards. I get under 2 MOA with Golden Tiger HP ammo and a bit over 2 MOA with Wolf Performance. Both group around an inch and a half high at 100. Have shot it out to 300 at 8” steel plates and can consistently hit at 250 and 7-8/10 hits at 300 holding at the top (12:00 position) of the plate

Only using PMAGS at this time. Had to “fit” a few to lock properly when inserted but not a big deal.

Zero FTF or FTE’s thus far after around 1000 rounds.

Pistol still shooting fine. Over 1K and no issues. Have no idea how accurate it is at any distance but up to 50 yards I’m hitting and happy.

But I’m no high speed guy, or someone me who is very familiar with an AK, so YMMV. I’m just an older guy who likes shooting fun guns...

The older bolts were all made out of Carpenter 158.

The newer 9310 bolts seem to be holding up just fine despite their thinner walls.

I've been running a 9310 Fail Zero bolt for 3500 plus rounds out of a 10.5 inch faxon barrel without any issues. 100% of those rounds have been with a Resonator K attached. The gun has had zero function related failures. If I pussy foot the charging handle I can induce a malfunction but when it comes down to the gun simply feeding, firing and feeding, its absolutely 100%.

I adore this thing.

Having said that, I am only shooting it because the price of 5.56 is insane. If price of ammo were no issue, I would absolutely without a shadow of a doubt be shooting a 5.56 gun as they are better in every way imaginable.

Also, for purposes of sharing data, I have been using Cproducts 28 round magazines.

One more thing to add. The gun was an absolute BITCH to get running right. Between buffers, magazines and gas block settings...holy shit, what a bitch. I had to drill the gas port out as from the factory, the gun would NOT run with ANY buffer and spring setup from standard car all the way up to H3's. Lastly, i've had some weird compatibility issues. The gun would not run with the cproducts magazines in a variety of GI and aftermarket upper receivers when mounted on my ADM SBR lower.

My only experience in 10.5 is my Alpha Shooting Sports. So far no issues.

x39 has it's advantage over 5.56 in some arenas. It's better for cutting down trees!

Just posting back, since all the insanity and x39 seems to be one of the few cartridge that can be had for a relatively reasonable amount Ive been waiting for a 10.5 ks47 to pop in stock, they did today so I snapped one up. We will see how it runs but from everyone talking here I dont expect anything major and if there are issues I should be able to take care of them relatively easily.

My new to me 43X, my new Canik TP9SFx, and my Extar9. I have shot a lot of ammo in my day. Never shot Blazer brass. It made me think the Canik was a single shot. It jammed like crazy in the Extar too. I have never had any problems out of the Extar, none! I swtiched to some steel case and both ran fine. Bro's G419 jammed on that Blazer too. He quit making fun on the Extar after that happened. It ran fine in the 43X. Too bad I couldn't hit a thing with the 43. @10yds it was shooting 8-10" level to the left. Front sight is crooked and couldn't be corrected. I need to order some night sights for it this weekend.

We got a late start as DHS was there for practice and you can't be there when they are shooting. They shot up a bunch of the purple tinted case 9mm Winchester and 300BO while they were there.

About dusk the "noseeums" got to eating us up! I didn't care.
