Cant beat the price. Front sight was very slightly chanted, cause I had to adjust rear right completely over to the left to compensate. I can put same sight on other upper and adjustments are minimal, (maybe 4 to 6 clicks either way).

Really nice kit. Super price.
Great kit to start with. Included everything needed minus the stripped lower. This is a lot of fun for plinking.
Daughter wanted something new to take to range. So we decided to build an AR from parts.

Good kit
Nice kit. Bought this and a stripped lower during their Easter weekend sale for $450 including shipping, and saved around $300 on the bundle.


Have probably 400-500 rounds through it now, not a single misfire or jamb. Holds decent groups with Federal 55g rounds, but with the 1:7 I am experimenting with heavier hand loads. Seems to like the 69 and 73 grain bullets more than the 55g.

Trigger pull is a touch heavy and "gritty". A polished trigger set would be a nice addition to the kit. I will be ordering the polished kit when it's back in stock.

Rear sight kit Cheap plastic... the rear sight on the M16 A2 I carried 30+ years ago is better than this. -1 star for the rear sight, other than that I would have given it 5 stars.

Overall great value if you can get it on sale.
