Raven Concealment TopStop AR-15 Upper Receiver Cover, Gray

The TopStop from Raven Concealment Systems is an upper receiver cover designed for use with AR-15 and M4-style uppers when detached from the lower receiver. It seals the upper receiver to limit the entry or exit of fouling and debris, and it prevents the bolt carrier group and charging handle from sliding out during handling. Built for storage and transport, the TopStop is well suited for spare uppers carried in low-profile bags or for keeping a bench workspace cleaner. The part is molded from a robust polymer and finished in matte gray for a low-profile appearance.
