AR-15 M16 A1 UPPER RECEIVER

AR-15 M16 A1 UPPER RECEIVER Reviews & Ratings

Designed in conjunction with Nodak Spud, the Brownells 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 Brownells 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 gray or matte black hard anodized finish. The gray finish mimics the original anodizing found on the early rifles. The black finish matches most modern lowers found on the market today, as well as the Brownells BRN-16A1 Lower Receiver sold separately. Upper receiver does NOT have M4 feedramps.

Standard AR-15 components 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


SPECS: Fits Standard AR-15 components. Finish: Matte black hard anodized. Profile: M16A1. Does NOT have M4 feedramps.

A1 upper receiver, sharp edges.
Very sharp edges, had to file ruining the finish on different spots. Cut my finger deep on top of carry handle.

out od spec
The fit and finish was excellent, but the carrier bore was way out of spec..My pin gauge set only goes to 1.007 and there was still a lot of slop..The spec is 1.000 to 1.006. The rear of the carrier has way to much slop, that can lead to broken bolts and poor accuracy..
