Frequently Asked Questions

Is this barrel ready to install out of the box? No, this is an unchambered blank; a gunsmith must chamber, thread, and fit it to your specific action.

Why choose the 20-inch length over the 24-inch version? The shorter blank trims weight and improves handling on a finished rifle, at a modest velocity trade-off.
