Sorry, had to take off for a b-day party yesterday.
So the parts are :
Barrel is a 1:7 heavy barrel/upper from Harden Arms.
BCG is AIM NiB
Buffer and buffer spring is I am assuming CMMG. I bought it along with the sb15 buffer type tube from ebay. I believe it should be a carbine buffer etc.
The ammo that was fired starting with my first failure to feed was cheapo wolf steel cased 55 grain, the second time was remington 62 grain , and the last where it wasn't a failure to feed but it was a failure to reset the trigger. No indent on case from pin hit or anything and that was with federal reloads 55 grain.
The gun is set up with only a a2 flash hider also. The LPK came from PSA not the PTAC cheapo stuff and it was installed by a gunsmith.
