The mount features a milspec drop-test rated 6061-T6 aluminum design, with an easy-to-use, one-handed, no-tools-required mounting system. The spring-loaded design allows for constant retention and maintaining of zero, even if the knobs are not tightened. The mount's 20 MOA cant provides additional elevation adjustment for long shots. The mount securely holds riflescopes with objective lenses up to 44mm on any firearm platform with a Picatinny rail.
