American Defense Picatinny Riser Features The American Defense Mfg. Picatinny Riser is built around the company s patented QD Auto Lock lever system which clamps firmly to Picatinny rails without needing a proprietary wrench or tool. The lever can be configured to lock toward the front or rear of the mount depending on a shooter s preference and fine adjustment can be made with a finger or a simple flat blade screwdriver. A wide clamping surface ensures maximum engagement with the rail holding the riser steady under recoil. At an overall length of 2.3 inches the riser accepts any 5 lug VPG bolt on rail accessory giving it broad compatibility with accessory rail systems already on the market. Machined from a solid block of 6061 T6 aluminum the riser is then finished in hard coat Type 3 Mil-Spec anodize for a tough long lasting black finish that resists wear from repeated mounting and dismounting. Raising an optic or accessory .60 to 1.2 inches above the rail surface helps achieve proper eye relief or co witness height depending on the host platform. The fully adjustable clamp design works equally well on rails that run slightly out of spec a common issue with aftermarket Picatinny sections. Backed by American Defense Mfg. s lifetime warranty and made with pride in the USA this riser is built to be a long term part of a shooter s setup.
