Samson Evolution Series KeyMod Free Float Handguard AR-15 Aluminum Matte

The Samson Evolution KeyMod Series free float rails are the next generation of rails from Samson. These handguards have all of the same features as the original Evolution Series, but have added KeyMod slots at the 3, 6, and 9 o'clock positions. The Samson Manufacturing Evolution Series free float rails are customizable AR-15 handguards. The Evo rail attaches to a standard barrel nut with a two piece thermal bushing constructed of stainless steel, two locking tabs ensure the rail does not rotate under stress. The thermal bushing along with the generous ventilation slots help to keep heat from transferring into the handguard and into the operator's hand. The continuous top rail allows you to mount optics anywhere along the top of the rifle and allows same-plane iron sights to be mounted. The top rail has also been relieved to accept most aftermarket piston conversion systems. The Samson Evo KeyMod handguards are compatible with all KeyMod direct attach accessories. Additionally, the interior of the tube is 1.56" in diameter, allowing most suppressors to fit underneath.
