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 heat shields 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. The 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.
- 2" and 4" rails available for additional mounting space.
- Optional aluminum top rails are sold separately for at the same height as flat top rail.
- Ambidextrous sling swivel mounts included.
- No gunsmithing required.
