Foxtrot Mike FM-15 GEN 2 13.9" Front Charging .223 Wylde Midlength AR-15 Complete Upper

The FM-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 FM-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 handle makes for fast reloads and weapons manipulation, as the handle can be placed on either side, up or downward facing, depending on your preference.  The monolithic type upper and MLOK free float handguard smoothly integrate, with the handguard also being easily removed for maintenance or swapping the charging handle.  

The lightweight 223 Wylde chambered barrel attached to the upper via an FM patent pending “taper lock” barrel nut, which has the interior face of the barrel nut integrate with a tapered shoulder on the barrel, providing more surface area to engage and more clamping force, ensure your barrel won’t shift!  The match grade 41v50 barrel has a 1-8 twist, and is available in a 13.9 inch length. The upper also includes 3 high grip MLOK rail covers, allowing for non-slip handling out of the box.  

13.9 inch Upper includes an A2 flash hider, which is NOT permanently attached.
