O-4M FUZE

The O-4M fuze is intended for use on 82 mm fragmentation mortar bombs fired from the BM82, 2B14, and for use on the OG-7 fragmentation grenade for the RPG-7V. It serves to detonate the warhead on impact with the target. The fuze is a nose impact type with two settings – for instantaneous (fragmentation) and inertial (HE) action, semi-boresafe, with distant arming.
