I’ve been so busy lately that I’ve not had a ton of time to go to the range but last week I specifically made time to hit the range and function test my 7.62×39 AR Pistol I built. This thing had been sitting in my HSP INCOG Rifle Bag completely ready to go just begging for some action and it was my pleasure to oblige. Below you’ll see some pics of my 7.62×39 AR Pistol. I’ll first cover the components I used to build it and the range report will follow after that.
Basically all you need to retrofit or build any AR upper as a 7.62×39 is the Barrel, Bolt and Mags and KAK Industry has everything you need in one place. I already had an extra AR Pistol lower built so I just needed some of their awesome upper components. The lower is a Noveske N4 forged lower with an ALG Defense ACT trigger, Battle Arms Development Selector, Magpul MOE K2 grip, Law Tactical Gen3 Folding Stock Adapter, Phase 5 Weapon Systems Pistol Buffer Tube and a Sig Sauer SB-15 Arm Brace. I upgraded to a Wolf High Power Hammer Spring but probably could have done without it.
For the upper I sourced the heart of the build at KAK Industry. They make all of their own components and have a great reputation. I used the KAK Industry 11″ 7.62×39 barrel, KAK Industry 7.62×39 complete BCG, KAK Industry Gas Block and Gas Tube. The upper receiver is an AERO Precision forged upper with a Northtech Defense Ti-FANG Titanium forward assist, Fortis Mfg Hammer charging handle, Centurion Arms 11″ CMR rail and a BattleComp BABC. Topped it all off with a Vortex Optics Viper PST 1-4 scope and an American Defense Mfg QD mount.
Of course the weather is changing up here in Michigan. It was cold and rainy that morning at the range but I couldn’t care less. I brought along some really nice Hornady 123gr 7.62×39 SST ammo to run through the brand new AR Pistol. The best thing you can do when function testing a new AR is to take it slow. I only had one ASC 7.62×39 mag so I loaded one round in the mag, pulled back on the charging handle, flipped the selector to “America” and pulled the trigger. As expected it went BOOM so I checked the chamber to make sure the rifle ejected the spent casing, which it did. After that first round goes as planned you get a bit of a smile on your face and start to have fun.
I loaded up another 5 rounds and proceeded to fire them down range sighting in the Vortex Optics Viper PST 1-4 scope. First 3 rounds went through perfect but on the fourth I had a Failure To Feed. Keep in mind I only had 5 rounds in the mag to start meaning this was the second to last round in the mag. I stripped the mag, removed the round and inspected it noticing that once the mag was removed the round didn’t really seem to be stuck or anything. I loaded another 10 rounds and again, second to last round FTF. This was a recurring theme and it became very clear that the issue was with the mag and definitely not at all a problem with the Upper, BCG or Barrel. Other than the second to last round of each mag issue I had absolutely ZERO malfunctions with this build. It really was a pleasure to shoot. I’ve heard the ASC mags get better as you wear them in but I will also be looking into some other brands and will do a followup article specifically regarding 7.62×39 AR Mags.
So after blowing through almost all of my ammo getting to know the 7.62×39 AR Pistol, I saved the last 5 rounds to get a little grouping on paper. Now keep in mind, when I test fire my AR’s I always go to the shorter range. Its basically a 30-35 yard range that typically has less people on it. When I shoot for groups I usually head on over to the 100 yard range but being that this is just an AR Pistol, I had no bipod, etc I decided to stay on the shorter range and just get a group there. The image below shows you a 5 round group, just resting the handguard on a block. I’m positive I could tighten this group up but I was out of ammo. One of these days I’ll get it out on the 100 yard range and get some longer range data. I was very happy with this group though based on the distance I would expect to shoot this rifle at in a real world situation.
Overall, I am very pleased with this build. Aside from the magazine issue, all of the parts functioned flawlessly. KAK Industry really is a one stop shop for tons of AR Parts including 5.56, 300BLK, 7.62×39, 458 SOCOM and .308 builds. This is not my first experience with KAK Industry and I’ve enjoyed every part I’ve purchased from them. For this specific build you can check out the KAK 7.62×39 AR Parts here.
