Is this the right barrel for your build?

This twist is matched to standard .22 rimfire ammunition. It's a target-weight contour that adds mass toward the muzzle to steady the rifle and help it hold zero as the barrel heats.

What a barrel blank is

A barrel blank is finished to your spec: your gunsmith cuts it to length, chambers it, threads the tenon to your action, and crowns the muzzle. Cutting a blank to length doesn't change its twist rate, so order for the finished length and profile your build calls for.

Keep it shooting

We recommend pairing your barrel with the ThorroClean Bore Cleaning System — fast, odorless bore cleaning that helps protect accuracy and keep the bore in top condition.
