The no tool UDC is constructed from high-density polymer for durability and functionality you won’t find in conventional dust covers, and it includes an adjustable detent screw to compensate for wear on the receiver. This also allows the user to increase or decrease opening power with a simple adjustment and a flathead screwdriver. The enhanced UDC features a flat dark earth finish for design and protection against corrosion. Pick yours up today and customize your AR’s dust cover!
