Wilson Combat® Ejection Port Cover Hardware Parts Kit – AR-15 – Black Steel – TR-EPDK
The Wilson Combat® Ejection Port Cover Hardware Parts Kit (TR-EPDK) is a premium, mil-spec replacement component bundle engineered to anchor an ejection port dust cover door to an AR-15 upper receiver. Produced under strict quality controls by Wilson Combat—one of the industry's most revered names in custom tactical firearms—this hardware pack (810025500283) strips away the guesswork from custom rifle assembly or field-repair maintenance. It delivers all the critical, high-strength small pins, springs, and retention clips needed to secure either a standard metal or upgraded polymer dust cover door to a forged or billet upper receiver housing.
Every piece within the TR-EPDK kit is machined from heavy-duty, heat-treated structural steel alloy to guarantee perfect dimensional compliance and fluid mechanical operation. The central hinge pin rod is ground straight to prevent the door from binding during its drop down cycle, while the spring is wound from resilient stainless steel wire to maintain crisp, instantaneous snapping action. Treated with a highly durable black oxide/phosphate finish, these components resist environmental corrosion, aggressive bore cleaning solvents, and high-heat carbon scale. Whether you are finalizing a premium scratch build or replacing a bent pin on a duty rifle, this package provides the raw structural reliability expected of the Wilson Combat name.
Includes: (1) Mil-Spec Ejection Port Cover Hinge Pin Rod, (1) High-Tension Return Spring, and (1) Retaining C-Clip.
*Please Note: This is the hardware mounting kit only. It does NOT include the actual ejection port cover/dust door. It is built specifically to install a bare door onto an AR-15/M4 style rifle chassis.
Key Features
