Double-Decker Short QD

The Bobro Engineering Double-Decker Short QD rail riser is designed to supplement an existing rail, giving you 5/8" of additional height and two quick detach levers for easy on/off the host firearm. It is very stiff, and the cantilevered end has a tapered reinforcement rib so that it cannot flex even under severe use. The entire riser uses 10 cross slots on a Mil-Std 1913 Rail with two machined in indexing lugs which enable the riser to return to zero when placed back in the same rail slots. It weighs 4.3 ounces, is constructed from 6061-T6 Aluminum, and uses our proven BLACR technology.
