Geissele SMR 10" M4 Handguard - Sand  (MOD 1 REV A)


 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 MK1 has threaded inserts along the rail that allow for the included rail sections to be directly installed on the rail, without the need for backing plates. Compatibility with gas piston systems is unknown at this time (July 2012).
