Raven Concealment TopStop Upper Receiver Cover, Grey

The Raven Concealment Systems TopStop Upper Receiver Cover in grey (Raven Concealment Systems part no. TOPSTPWG) snaps onto a detached AR15 or M4-type upper receiver, rounding out the TopStop color lineup for shooters who run grey furniture or simply prefer a neutral tone. Raven Concealment Systems built the TopStop to solve a real problem for anyone who separates the upper and lower for cleaning, maintenance, or shipping: an exposed upper invites dirt and moisture, and the bolt carrier group can slide free and get damaged or lost in the process. This grey colorway seals the upper receiver just as completely as the other TopStop finishes, preventing fouling from getting in or out and locking the bolt carrier group and charging handle in place while the upper is handled or transported.
