Raven Concealment TopStop Upper Receiver Cover, Black

The Raven Concealment Systems TopStop Upper Receiver Cover in black (Raven Concealment Systems part no. TOPSTPBK) snaps onto a detached AR15 or M4-type upper receiver to keep it clean and protected during storage, transport, or a build in progress. Raven Concealment Systems designed the TopStop around a common problem for anyone who works on or stores AR uppers separately from the lower: dirt, debris, and moisture can get into an exposed upper just as easily as a bolt carrier group can slide out and get lost or damaged. Once snapped in place, the TopStop completely seals the upper receiver, preventing fouling from getting in or out while also stopping the bolt carrier group and charging handle from sliding out as the upper is moved, packed, or shipped.
