CUSTOM TRANSFER SLEEVE for Crosman 13XX, 22XX & Discovery

$15.50

The inside diameter is about .150" to match our Magnum Valves.

With standard Discovery, 22XX and 13XX valves, this custom steel transfer sleeve helps compensate for misalignment of the ports. This is often caused by the valve-port hole in the tube being out of alignment which seats the gasket off-center to the valve port.

 Compared to a standard steel sleeve, it increases air-flow volume for more power and better shot-to-shot consistency.

 It fits 1377C, PC77, 1322C, P1377, P1322, 2289G Backpacker, 2240, 2250B, 2260, 2300T, 2300S, Benjamin Discovery, Crosman Custom Shop and other related models. The photos show the custom sleeve on the right compared to a stock sleeve on the left. The custom sleeve is chamfered on the inner edge of the valve side to smooth air-flow.

 It will not work with the older 1377, 1322, 1400 or similar models that have a sliding breech cover.
