BSF Barrels 22 Caliber 20" 1:7 Twist Rifle Barrel

A 22 caliber bore barrel from BSF at 20" with a fast 1:7 twist, listed for bolt action rifles. A 1:7 rate is the fastest of the common .22 twists, and it exists to spin the longest and heaviest projectiles in the bore rather than light varmint bullets.

Twenty inches keeps the rifle a reasonable length while still letting a .22 centerfire case get up to speed. Bore, length and twist are the specifications given here. Chamber, shank diameter and muzzle thread are not listed, so confirm them against your action before ordering.
