Timber Creek billet dust cover in black has more heft than stamped covers. Install required the c-clip wrestling thats common with dust covers, no instructions in the package. Once seated spring snaps door open positively.
Billet ejection port cover from Timber Creek has heft and a cleaner profile than the stamped factory ones. Black Type III anodizing took a couple hard impacts during a class without showing wear. Snaps open positively. Worth the extra over a cheaper cover.
Timber Creek black billet dust cover is well made with even anodize. Spring snaps the door open on bolt cycling. Heavier than a stamped cover. Comes complete with the c-clip pre-installed. Drop in install once the upper is stripped.
same billet cover in black, same review basically. thicker than stamped, snaps clean, hardware in the box. one of those parts where spending 10 more bucks over a stamped cover gets you a noticeably nicer piece
