Norotos mounts

A quick look at a couple different Norotos mounts, with helmet attachment options. Also a look at the USGI J-arm (Bayonet style lockup) vs the WILCOX version of the J-arm (NVG Shoe style lockup) . There are two versions of the USGI J-arm (you can tell them apart by the small screw in the center of the thumb screw where it attaches to the pvs-14 -- that's the newer model). There are also two versions of the Wilcox PVS-14 Arm (2nd version has Auto Off Switch).
