Cylinder Sleeve - 4.250 ID 7.000 Length

The Cylinder Sleeve – 4.250 ID 7.000 Length is a precision-engineered cylindrical component designed for law enforcement, military, and specialized tactical applications where reliable bore protection and alignment are critical. This sleeve serves as an essential interface in firearm assemblies, providing structural integrity and precise dimensional control for systems demanding exacting tolerances. Built to withstand the rigorous demands of duty carry, training, and field operations, this component is engineered for professionals who require uncompromising performance.

Manufactured to OEM specifications, the Cylinder Sleeve features a 4.250-inch inner diameter and 7.000-inch overall length, delivering the dimensional accuracy necessary for proper cylinder seating and repeatable alignment in high-performance applications. The substantial 2.95-pound weight reflects solid steel construction designed to absorb recoil impulse and maintain shot-to-shot consistency under sustained fire. Precision machining ensures concentricity and surface finish quality that prevents binding, galling, or premature wear—critical factors in duty weapons where reliability cannot be compromised. The compact 5.1 x 5.1 x 9.6-inch profile allows seamless integration into standard tactical platforms without interfering with ergonomic controls or accessory mounting.

This cylinder sleeve is ideally suited for armorer-level maintenance, platform upgrades, and OEM replacement cycles where factory-equivalent performance is non-negotiable. Whether used in duty pistol builds, competition setups, or military small arms maintenance programs, proper installation ensures bore alignment and cylinder runout remain within specification. Compatibility with most modern tactical platforms makes this a go-to component for gunsmiths, law enforcement armorers, and military ordnance specialists performing cylinder replacement or upgrade work. Always verify dimension compatibility with your specific firearm platform before installation.
