PROOF Research PXT .264 16.5" Sendero Carbon Fiber Barrel Blank

A blank is raw material. This one arrives rifled but unchambered, so a gunsmith cuts it to your finished length, reams the chamber you asked for and threads the muzzle before it goes on an action.

At .264 bore and 16.5", this blank suits a short, suppressed 6.5 build where the can adds the length back. The Sendero contour gives a gunsmith plenty of steel to work with at the shank and under the threads. PROOF wraps a match grade core in aerospace carbon fiber, so the finished barrel resists heat and holds zero as it warms rather than walking shots. PXT rifling accelerates the twist through the bore to ease the bullet into the lands.
