FOXTROT MIKE .300 BLK FM-15 BUFFERLESS UPPER RECEIVER

This is the long awaited 300 BLK version of Foxtrot Mikes' widely popular bufferless upper receiver for the AR platform. Use with any standard AR lower receiver, on the Foxtrot Mikes Ranch Rifle, or the A3 Tactical TRIAD Bullpup system!

The Foxtrot Mikes Products FM-15 Gen 2 Side Charging AR-15 Upper Receiver features a unique dual spring recoil system nested in the top of the upper receiver allowing the use of a folding stock. This recoil system is paired with a direct impingement gas system and a proprietary lightweight bolt carrier group for a smooth and reliably functioning rifle. The gas block features an indexing pin and a coil pin to keep it locked in place against the lightweight contoured barrel for an extremely robust system.
