Does NOT have M4 feed ramps. M16A1 Upper Receiver matches the features of the original M16A1 Receiver. Perfect for a Retro or reproduction build, these uppers precisely mirror the original profile. This match is only possible by utilizing forgings with the proper profile built-in.

Features specific to the M16A1 Upper Receiver are the original A1 profile, with no shell deflector, A1 rear sight housing and proper carry handle contours. The upper starts off as a 7075 T6 aluminum forging, then is machined to mil-spec dimensions. Once machined, the upper is finished with a matte black hard anodized finish. The black finish matches most modern lowers found on the market today. Standard AR-15components will work perfectly with this upper.

This upper is the proper receiver for the following reproduction builds: XM16E1 M16A1 Model 607 Model 609 (XM177E1) Model 619 Model 629 (XM177E2) Model 639 Model 651 Model 653
