DESCRIPTION

The Arken Optics Precision 20 MOA Picatinny Cantilever Mount – 2.5 inch offset – 34mm is engineered for shooters who demand accuracy, stability, and enhanced eye relief on AR-style platforms. Offering 2.5 inches of forward extension, this mount ensures optimal positioning for scopes, particularly when using rifles with limited rail space. The 20 MOA cant provides additional elevation adjustment, ideal for long-range shooting applications.

Crafted from aircraft-grade aluminium and fully CNC machined, the Rigid Precision mount delivers exceptional durability and tight manufacturing tolerances for a secure, repeatable fit. With a tube size of 34mm, 1.5-inch height, and weighing just 7.1 oz, it offers a strong yet lightweight solution. Arken recommends torque settings of 18 in/lb for ring screws and 30 in/lb for base screws, though users should defer to their optic manufacturer’s guidelines if higher.

MOUNT SIZE GUIDE

Ring Height Calculator

This calculator works out the minimum ring height (base-to-centre) you should use, including a tolerance allowance.
Please note: All clearance calculations are based on mounts with 0 MOA. While MOA can be factored in, actual clearance may vary due to variables that can't always be accurately calculated. If you're considering an MOA mount and are unsure about the required height, we recommend contacting our sales team directly.
