AR15 Stripped Upper Receiver - Anodized Black (BLEM)
- Product Review (submitted on July 12, 2015):
- I have bought 4 of these and the blem I assume is the "A" on the side isn't perfect. Fit and function is spot on as are all AERO parts. I own and have built many AR's with AERO parts, none have had any fitment or function issues of any kind. This is the main brand I recommend to anyone building a AR.
