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.
Installation of the Evolution series handguards does not require special tools. Since the standard barrel nut (not included) is used to mount the handguard only the delta ring, weld spring and snap ring must be removed. This means you can install the EVO rail system without removing the barrel from the upper receiver, a step that requires specialized tools such as receiver blocks, barrel nut wrench or AR-15 multi-tool. The delta ring must be cut if you do not remove the barrel from the upper.
