Dead Air's flash hider has a unique design featuring mass shifted equal length tines. The end result is a flash hider that does not "ping." It is compatible with our Sandman Series and KeyMo equipped suppressors. The KeyMo flash hider is also compatible with our KeyMicro equipped Wolfman. When it comes to removal, the suppressor can be easily removed without carbon-locking onto the mount. Weight: 3.6 oz. - 4.0 oz.Note: To mount your suppressor to a KeyMo flash hider it must be equipped with a KeyMo adapter or KeyMicro adapter (sold separately).Bore Diameters: 1/2-28.224 caliber (Part #: DA301) 5/8-24.30 caliber (Part #: DA302) 9/16-24LH or RH.30 caliber M14-1LH.30 caliber M15-1.30 caliber M13-1LH.224 caliberCompatible Supressors: Sandman series Nomad series with KeyMo adapter Nomad-Ti series with KeyMo adapter Primal with KeyMo adapter Wolfman with KeyMicro adapter.; 810128160445
