The Primary Arms 34mm PLx Cantilever Mount is an angled mount that allows you to mount a scope with a 34mm barrel, with the aiming point at 38.1mm. It provides a wider eye relief and therefore a wider field of view and better situational awareness. Another advantage of the cantilever mount is the ability to use a running scope and a collimator (with an angled mount) or mechanical sights simultaneously. The 20 MOA tilted model allows the scope to be zeroed at a greater distance, which is especially useful when shooting at long ranges or in situations where the scope no longer offers vertical adjustment.Primary Arms 34mm PLx Angle Cantilever Mount - 1.5" Height - 20 MOA - Rugged and LightweightThe element is lightweight (175 grams) so it does not noticeably increase the weight of the carbine. The body is made of rugged anodized 7075 aluminum, while the bolts are made of 12.9 low alloy steel, which has high tensile strength.
