Strike Industries Ultimate Dust Cover | .223/5.56 | Enhanced Version Style 03 | FDE

The SI UDC enables users to attach and detach the cover in 5 to 10 seconds with ease (stock dust cover will take more time to remove)! It is constructed of a high-density polymer making it more durable and functional than the traditional dust covers. The Ultimate Dust Cover features an adjustable detent set screw in order to compensate wear on the receiver and increase or decrease opening power (To adjust detent: use small flathead driver and depress the ball detent and adjust as necessary.). Choose multiple designs to customize your AR! 

NEW features of the Ultimate Dust Cover Enhanced Version include the added cut-out window on the rod for easy disassemble and that it has been made thinner than the original to be compatible with all AR15 receivers on the market and at the same time makes it even lighter weighing in at only 0.3oz! Additionally, The "True Seal" Lip has been slightly modified to provide an even better seal than ever before! The UDC-E (Ultimate Dust Cover- Enhanced Version) is the modified version of the original UDC for mil-spec receivers. 

*Strike Industries strongly recommends applying blue Loctite threadlocker to the ball-detent thread after being adjusted.
