Nice kit for good price.

Initial impression is very good.
I picked this up during a sale because with the SOB pistol brace the price couldn't be beat. This was the second AR lower I've built on Anderson lowers. The Upper came completely assembled.

Probably the most important point for me is reliability. While my range time was short I ran 210 rounds of brass cased ammo through the pistol. I used magpul tapco and ETS mags. I shot 30 rounds precision 60 rounds of two to the chest and one to the head and the last 180 were rapid fire with speed reloads. By the time I was done the front hand-guard was too hot to hold with a leather and flame retardant glove on but there wasn't a single malfunction. I was concerned due to the 7 inch barrel but it ran like a top. As far as accuracy I only had some cheap plastic sights to throw on it at the time. I can't describe the MOA of the weapon but it's more than enough for Minute of Badguy if need be.

Other points of note: The BCG was impressively clean after shooting It has a very smooth coating on it. It was loud I am definitely going to pick up a KAK can for this weapon. On this build the pivot pins are much easier to manipulate and the trigger on the PSA built is 3 times as good. it is smooth with no grit at all. This was a very positive surprise.

Long story short I think this was a great buy and I would absolutely do it again. Nice work PSA.
