Command Arms M4S1 Handguard & Rail System for AR15/M16 Carbines Product Info

The Command Arms M4S1 Handguard is a front handguard system for M16 and AR15 weapon systems, and includes a bottom rail and two side rails. The two-piece hand guard features interlocking top and bottom pieces, the bottom portion equipped with a Picatinny rail that can be mounted to the existing sling swivel mount for extra stability.

Helpful Positive Review Great look, fit and function...and one myth! by C. Ray, May 9, 2015
Nothing that looks this good is available for ARs with delta ring hand guards. It is virtually impervious to heat (but doesn't have metal heat shields). I have two lightweight builds that wear them. The whole assembly weighs less than half a pound...
