Arken Optics Rigid Precision Cantilever Mount Features The Arken Rigid Precision Cantilever Mount is fully CNC machined from aircraft grade aluminum giving it tight tolerances that help maintain a consistent zero shot after shot. The cantilever design extends the optic forward of the receiver providing roughly 2.5 inches of additional eye relief that is especially useful on AR style platforms with shorter stock positions. This mount is sized for a 34mm scope tube a diameter increasingly common among modern precision riflescopes that need the extra internal travel a larger tube provides. With a 0 MOA configuration this mount is intended for rifles where the shooter does not need the extra elevation built into a graduated base keeping the reticle centered in the optic s travel range for closer to mid-range work. Arken recommends torque settings no greater than 18 in-lb for ring screws and 30 in-lb for base screws to avoid damaging the optic or mount. At 5.9 ounces the mount adds minimal weight to the rifle while delivering a rock-solid mounting platform. This combination of precision machining and thoughtful design makes the Rigid Precision Cantilever Mount a strong option for sale at GrabAGun.
