Luth-AR UR-01-E3-S A1 Stripped Slick Side Upper Receiver – 5.56/.223, 7075-T6 Aluminum

Build or restore a period-correct retro AR-15 with the Luth-AR UR-01-E3-S A1 Stripped Slick Side Upper Receiver. Forged from 7075-T6 aluminum to mil-spec dimensions, this upper captures the authentic early-style carry handle contours and A1-pattern rear sight housing that serious retro AR builders demand.

The slick side design intentionally omits the forward assist and shell deflector, staying true to the original A1 profile. All attachment points are machined to current mil-spec tolerances for compatibility with standard AR-15 components. Note: this upper does not include M4-style feed ramps, making it the correct choice for period-accurate retro builds rather than standard flat-top configurations. The black hardcoat anodized finish delivers outstanding durability and long-term corrosion resistance.

Please note that the charging handle, dust cover, and rear sight components are sold separately.
