Proof Research Sig Sauer CROSS 22 Creedmoor 20" Carbon Fiber Barrel

This Proof Research prefit barrel fits the Sig Sauer CROSS and is chambered in 22 Creedmoor, a fast, flat shooting 22 caliber round. It is 20" long with a 1:8 twist and a 5/8-24 threaded muzzle, and it comes with the barrel extension, so it swaps onto the CROSS without a gunsmith.

The carbon fiber wrap is up to 64% lighter than a steel barrel of similar contour and moves heat away from the bore, which helps on a lightweight rifle like the CROSS.
