Billet-Like Slick Side Upper for Lightweight AR-15

Aero Precision now offers the M4E1 version of their assembled slick side upper.  You get the sharp angles and sleek facets typical of billet receivers, with the light weight and durability of forged aluminum.  You also save weight, with lightening cuts on the top rail, and a lack of forward assist.

All the essential dimensions on this upper are the same as on a traditional forged receiver.  Most handguards with anti-rotation features fit above the barrel extension with no modification.

This receiver is also a perfect match for the ATLAS R-One handguard.  Check it out if you’re doing a new upper build!
