Command Arms Accessories is proud to present the NEW M4S1 M16/AR15 carbine handguard sets the standard for a stable and rigid design by combining interlocking top and bottom handguard sections with a bottom rail that can be mounted to the existing sling swivel mount for absolute rigidity. The M4S1 handguard will not move once locked in place providing repeatable zero.
This is the first lightweight polymer handguard designed to withstand the extreme operating temperatures of a gas piston system. This extreme heat resistance is achieved by manufacturing the M4S1 from a proprietary heat resistant polymer, including a heat shield and providing significant upper and lower handguard venting in the design. The M4S1 also works with standard direct gas operating systems.
The M4S1 includes two interchangeable lower rails of 4″ & 1.75″ lengths. This allows the operator to quickly change rails based on mission need. The two 1.75″ side rails are removable if not required. Even with the side rails attached there is enough room left on the contoured handguard for your hand to hold it comfortably. An optional 9″ long aluminum top rail attaches to the handguard and flat top rail providing a super stable platform for mounting optics and sights. The M4S1 also includes two mounting points for a push button quick detach sling swivel.
– 1.75″ and 4″ bottom rails allows for quick rail changes.
– Optional 9″ aluminum top rail provides stable optics platform (M4S1T).
– Ambidextrous sling swivel mounts included.
– No gunsmithing required.
