Geissele 15" MK2 Handguard - Black  (Mod 1 Rev B)

The SMR is designed to fit M4 Carbine mil-spec flat top upper receivers and must be used with a low profile gas block. Non mil-spec upper receivers, such as billet upper receivers, may need to have gunsmith modifications made to the SMR to fit properly. The MK2 Handguard includes three rail sections that install via one-piece backing plates that fit within tracks on the inside of the rail. Compatibility with gas piston systems is unknown at this time (July 2012).
