Troy’s revolutionary free float two-piece modular and quad rail drop in rail system requires no Gunsmithing to install, requires no modification to the firearm, has two built in Q.D swivel mounts, and free floats the barrel for improved accuracy. This two-piece rail system installs in minutes and offers and extended forearm while allowing the user to keep the existing fixed front sight post. The Charlie rail system features four full-length Picatinny rails with an extended tube past the fixed front sight. The Delta modular rail system allows the user to add smaller rail segments (Not Included) to the rail where needed without having the added weight of a full-length quad system. Troy’s new drop-in free-float rails are built off a rock solid rotary clamping system; do not require removal of the delta ring, barrel nut or fixed front sight.
SPECS: Aluminum construction, matte black anodized finish. Fits carbine length AR15/M16 gas system barrels with a fixed front sight base. Mounts to existing AR15/M16 barrel nut and does not require the removal of the delta ring assembly.
