From the manufacturer
The Mike-15 Upper Receiver incorporates several novel and patent pending ideas into one of the most innovated AR-15 uppers on the market. The integrated, proprietary recoil system allows for the upper to function without the need for a lower with a buffer tube. This upper can function just fine with a stock or brace folded! The included Picatinny adapter adapts any standard AR-15 lower to a Picatinny style stock or brace (purchased separately). The Mike-15 includes a patent pending, fail proof mid-length gas system, that drastically reduces gas leakage and removes any concern about a gas block coming loose. The patented 4-position, non-reciprocating front charging ha Mfg: Foxtrot Mike Products
