Barrel

Barrels are made from 416 stainless steel, hand-lapped and hand-chambered. Each chamber is machined to run both Eley and Lapua length rim thickness, allowing consistent ignition across precision-oriented rimfire ammunition. Crush on the projectile is optimised by engaging the second drive band on the bullet across multiple bullet types, enhancing accuracy performance.
