Endcap for mounting stocks and braces designed to attach to a picatinny (1913) rail on your SMG45.
Built-in QD sling mount.
Machined from 6061 aluminum and hardcoat anodized black (Mil-A-8625 Type III Class 2).
Fit Issues: If you are having fit issues, the rear takedown lug may be to blame. This is the part on the receiver that the rear takedown pin passes through. Loosening the 4 torx head screws that secure it may allow the part to move enough to correct the issue. Once proper fit is achieved retighten the 4 torx head screws.
