Now available is a like-new original Leatherwood ART/MPC scope on a Weaver mount. The bullet-drop compensator cam (7.62mm) is the same as the ART II. These were made right here in Texas, not you current (Hylux) Chinese crap. The ART TEL and II were designed on an M14 mount. The MPC was designed on a Weaver mount so that it could be utilized on other sniper rifles with Weaver rails (picatinny hadn't been developed yet). It could also be mounted on an M1a/M14 type rifle using an older mount with Weaver cut rails (I have these too).
Instruction manual included.
Also available are cams designed for other calibers: .223, .30-06

M14, M1 Garand, and AR parts available too.
