Standard Upper Features:

This Stripped Slick Side A1 Upper Receiver is made from 7075-T6 aluminum forgings machined to final dimensions. Correct early-style carry handle contours with A1-pattern rear sight housing. The Slick Side A1 Upper eliminates the shell deflector and forward assist. Dust cover, charging handle and rear sight components sold separately. All points where other parts attach are finished current mil-spec dimensions. Current production AR-15 components will fit perfectly.

Note that the AR-15 / M16 Slick-side Upper Receiver is period-accurate therefore it DOES NOT have M4-type feed ramps found on most current-production AR-15 flattop upper receivers.
