Description
RTB 9mm / 22LR Slick Side Upper Receiver
This .22LR / 9mm upper receiver assembly is made from forged 7075-T6 aluminum and is Hard Coat Anodized. It meets military specifications and comes in a slick side configuration.The ejection port door is sized for 9mm and 22LR.The brass deflector is kept in place to help protect you face from gas blow back.
.22LR and 9mm AR builds both use direct blow back, which creates more gas to the face than usual.Although the brass deflector is not necessary for these two calibers, it helps mitigate gas to the face.
- Machined from a Mil-Spec 7075 T6 forging
- Type III Hardcoat Anodized finish
These uppers are machined to extremely tight tolerances for a more accurate build.Seating the barrel may take additional force.Light taps with a rubber mallet will do the trick.
