    Ordered a few various kits from here… Recently this was one of them. Finally got to test fire it. Did well. Only downside is trying to remedy the issues that are existent with 300 aac rifles & pistol kits… Used a Century arms mag a relative from military has from his time in the Marines. Had one issue with it not grabbing a round from the mag to chamber but I believe that’s from the poor follower tilting.. No ejection issues. Did have misfire issues which I’m not sure if it’s related to the manufacturer of the rounds I fired (Remington 220gr) but only 3 out of 20 which did fire when I re-chambered it. I do recommend to do a little polishing to the feed ramps and try wearing in the BCG with the upper and barrel as much as possible before first time firing.

    Overall I’ve always been happy with all the other kits I’ve ordered.
