LEUPOLD MARK IMS SCOPE MOUNT The Leupold Integral Mounting Systems (IMS) family quickly and easily eliminates the two most common issues faced when mounting standard riflescopes to AR-style rifles; scope height and eye relief. Each aluminum IMS cantilever design mounts directly to the firearm's Mil-Spec 1913/Picatinny to raise the scope and push it forward, eliminating the need for risers or specialized optics with shortened eye relief. Easy-to-grasp A 1/2" hex nuts on the crossbolts for quick release removal and installation. CONTENTS Mount, torx wrench & instructions in a cardboardbox. SPECS Tube OD: 34mm Length Mfg: Leupold
