The SLR (Slim, Light Rail) was designed as a slimmer handguard that can accept most aftermarket piston systems. This rail is 5/8" slimmer than YHM's current series of handguards. The new profile of the SLR allows for most piston systems to be used while maintaining a top rail that co-witnesses with the upper receiver. The top rail has been redesigned to create one continuous picatinny rail between the upper receiver and the handguard. This rail can also accept the customizable rails that YHM currently offers. Rail can be mounted with out any special tools required.
Barrel nut, allen wrenches, and installation instructions included with purchase.
