The SLR (Slim, Light, Rail) series handguards by Yankee Hill were designed to be thinner and accept most aftermarket piston systems. The SLR profile allows the use of most piston systems while still maintaining a top rail that co-witnesses with the upper receiver.
With this rail’s new design, when installed it creates one continuous Picatinny rail and a new mounting system method for attaching the handguard to the receiver. This means you will not need any extra tools to install the new SLR handguards. This high-quality customizable Yankee Hill rail was proudly made in the USA is what you have been anxiously waiting for.
