The CQBL-1 is based on the popular laser module made by SD. The CQBL-1 is made using CNC aluminum and topped off with a hard coat anodized finish, making it very lightweight yet robust. The CQBL-1 features a co-aligned visible Green and IR laser, which eliminates the need to sight-in each laser individually. The low profile controls like the windage and elevation adjusters ensure a constant zero and reduces the risk of snagging your weapon platform on obstacles. The CQBL-1 is one of the smallest and most rugged dual-function laser modules available and is specifically designed for close-quarter combat. This laser aiming module is perfect for submachine guns and short-barreled rifles or anything compact.This product is only suitable for airsoft guns
