Overall, I'm pretty happy with the results.I put out about 300 rounds, I DID have some issues. My rifle wouldn't cycle Wolf 75 grain hp, or Brown bear 62 grain hp. Also another brand that I can't id its headstamped fc (maybe,hard to make out).It shot Remington stuff without a hiccup, as well as S-B.
 The ftf stuff, out of 9 rounds, 3 have a light primer strike, the rest failed to cycle. I've read that some of the Russian stuff was underpowered, and would fail to send the bolt back far enough to pick up a round. For now, I'm assuming this was my issue.
My barrel is a twenty inch Colt hbar.All my mags are brand new Pmags. My bcg is PSA FA, and my buffer and spring are oem Colt (from a 20 inch Hbar).
 Any advice or suggestions are appreciated,thanks.

It sounds like you may have your trigger spring installed wrong or "upside down".  Take a look at the picture in this link––-

Is yours installed correctly???

I would just stick to whatever is working and get a good base, then go back and try the Russian stuff and see if it is an ammo related issue. I would be leaning towards the ammo before the rifle.

Its probably fine. Run 1k rounds of good quality ammo through it that it likes, get it a little broke in then try shooting some of the cheaper stuff. Some rifles just wont run the cheaper .223 ammo. I wouldnt worry to much about it yet. SHOOT IT!    LOL!

That's what I thought. I've got a thousand rounds of WPA coming tomorrow.
