Description
The Warne V4002M is a one-piece cantilever scope mount from Warne’s Vapor line, made for 30mm scope tubes on AR-style modern sporting rifles. It slides onto a MIL-STD-1913 Picatinny rail at least 2.5 inches long and fits the AR-15, M-4, SR-25, LR308, PTR-91 and similar MSRs, positioning the scope forward for correct eye relief with low-power variable optics and modern riflescopes.
The mount is machined from aluminium in a matte black finish and weighs 4.7 oz (approx. 133 g). Warne lists the dimensions as A = 30mm (tube), B = 1.40 in, C = 0.750 in and D = 3.05 in, and states it clears objective bells up to 72mm. Cross-bolt torque should not exceed 30 in-lb on dry threads with no thread locker; ring cap torque follows the scope manufacturer’s recommendation. Made in the USA and backed by Warne’s lifetime warranty.
