The Brownells Threaded Sleeve for Savage Large is a precision component designed specifically for Savage Arms actions in RUM, RSUM, and WSM calibers. This sleeve measures 3¾” (9.5cm) in length and weighs ¾ lb. (340 g), making it a compact addition to your gunsmithing toolkit. The sleeve is engineered as part of the Brownells bolt lapping tool system, enabling gunsmiths to achieve precise bolt lug alignment for improved accuracy and receiver fit.
The spring-loaded tool provides constant, straight-back pressure to keep bolt lugs square against the receiver while lapping with 600 to 800 grit silicon carbide abrasive, delivering better results than mere thumb pressure. The interchangeable threaded sleeves design fits popular actions, making this sleeve a versatile accessory for multi-action gunsmithing operations. Whether you’re working on your personal build or professional restorations, this Brownells sleeve delivers the precision control that serious gunsmiths demand.
