Description

The caliber conversion kit is the factory solution for shooters looking to move up to the .30 caliber. It features the Superlight STX system, where the liner is held in place by the outer shroud rather than a heavy steel sleeve, significantly reducing the front-end weight of the rifle. The 600mm length is the “Standard” length for .30 caliber Crowns, providing the necessary air expansion to stabilize heavy 44.75gr to 50.1gr pellets.

The kit includes a Superior STX Liner, which is optimized for standard pellets but can be easily swapped for “Slug Liners” if desired. Unlike the “Barrel Only” kits, the caliber conversion bundle ensures you have everything needed for the swap, including the larger .30 caliber magazine and the matching brass or steel pellet probe.
