I bought 6 of them, and my buddy 3. All from AIM, and all were flawless. Nice finish, no cut corners on the seams, no dings on the forgings, and pmags drop free in all 9 of them. Best 300$ I've spent this year
. They look just as good as my Spikes and Aero lowers. These are definitely not craptastic lowers with visable forge marks under the grip, trigger, and front of the magwell........they are finished nice. Besides the barrels, bushmaster stuff is as good as anything else on the shelf IMHO. I haven't had issues with any of the extraneous parts I have from them. Lots of misplaced hate for them after they fudged the Masada
The only thing I noticed at all with building them, is the bolt catch roll pin went in pretty easy in a few of them. Coulda been the roll pins though, and that pin really doesn't have to be sledge hammer tight anyways. I used a combination of PSA, CMMG, and even a DPMS kit, and all the LPK's worked just fine.
