So after helping my brother in law put together a couple of rifles for himself and a buddy, I got the itch to do one for myself. Since I already have one in 5.56 I decided to do it in 7.62x39. Picked up a Anderson lower from a fellow ingo member, and ordered a 16" flat top rifle kit from Blackthorne. The rifle kit made it to my door in 3 days, pretty quick shipping. After inventorying all the parts and getting it assembled, I took it over to a buddies to try it out. Not to shabby, it shot about the same as my 5.56 rifle but had a few ftf issues. After field stripping it to clean I noticed a lot of copper build up on the feed ramps. They looked a little rough where the barrel and upper receiver meet. A small amount of touch up with a small grinder cured that problem. I got 2 30 round ASC magazines for it a few days after the first range session. More ftf issues, wouldn't chamber the last 3 or 4 rounds out of both mags. A set of Wolff ak47 mag springs fixed the problem. I'm happy to say today we ran 125 rounds of steel case ammo through it today without a hiccup. This gun is tons of fun to shoot and I can't wait to spend some more time at the range with it.
