This is a mil-spec M4 RAS, which is identical to the Knights Armament RAS, but is made by P&S Products. Both KAC and P&S are DOD military contractors, and are providing the same RAS to the military. Thus, they are the same, but P&S saves you a few dollars. Military Surplus. Comes with P&S rail covers. Again, the same style and look at Knights Armament. Interchangeable. If you want KAC covers, we sell those as well.
At Charlie's we mostly use these in builds. From time to time we have a few extra that we make available for sale.
Note: Does not include rail covers.
