Strike Industries Ultimate Billet Dust Cover for AR-15/M4/M16 – Black

The Strike Industries Ultimate Dust Cover (brand part number ARBUDC223BK) is a heavy-duty billet aluminum dust cover built for AR-15, M4, and M16 pattern rifles. Strike Industries machined it with a quick-detach mechanism that lets you install or remove the cover in under 10 seconds, along with an adjustable detent set screw that compensates for receiver wear and lets you fine-tune opening power. Patent-pending noise-reduction padding makes the cover nearly silent during activation, a real advantage for hunters and anyone running a suppressed or subsonic setup where a loud dust cover slap gives away your position. It includes four rubber pads in the box, and Strike recommends applying blue Loctite to the detent screw threads after adjustment. Note that it isn’t compatible with Aero Precision M4E1 upper receivers or the LanTac E-BCG, due to differences in carrier and bolt design.
