Screw In Oil Cap

The SPECTRE Screw In Oil Cap (SPE-4320) is a precision-engineered replacement component designed for firearms requiring tool-free maintenance and fluid retention. This compact cap serves as an essential part of any operator's maintenance kit, whether you're conducting field-strip cleaning after a training evolution or performing routine preventive maintenance on duty weapons. Built to tight tolerances, the screw-in design ensures secure sealing without requiring additional tools or adapters, making it indispensable for rapid equipment turnaround in tactical environments.

Engineered by SPECTRE—a brand recognized throughout law enforcement and military procurement channels—this oil cap employs direct screw-in threading for reliable hand-tightening and positive retention. The precision-machined design prevents cross-threading and ensures consistent sealing across repeated service cycles, a critical factor when storing weapons for extended periods or maintaining readiness standards. Weighing just 0.105 lbs and measuring 3.75 x 1.5 x 5.75 inches, the compact profile fits easily in maintenance kits, cargo pockets, or gun cleaning bags without adding bulk to your loadout.

This cap benefits firearms operators, armorer personnel, and military maintenance teams who require authentic OEM-equivalent components for their weapon systems. The screw-in mechanism eliminates fumbling with loose caps during field maintenance, reducing the risk of lost components in austere environments. Installation is straightforward—simply hand-tighten into the threaded oil port on compatible firearm actions until snug; no specialized tools or gunsmithing required. Ideal for both defensive carry weapons and duty rifles, the SPECTRE Screw In Oil Cap provides peace of mind that your firearms remain properly sealed and protected between cleaning cycles.
