Geissele 6.5mm MTU Cut Rifle Barrel Blank 30-1313-2700-264-075-01-B

For anyone building a custom 6.5mm rifle from the ground up, the 6.5mm MTU Cut Rifle Barrel Blank 30-1313-2700-264-075-01-B gives a gunsmith exactly what's needed to start cutting: a precision pre-contoured barrel blank, manufactured in the USA from high-quality barrel steel, with a 27.00-inch overall length and an MTU Cut profile built around 6.5mm (.264) builds. This isn't a finished barrel — it's the raw foundation a smith works from to cut the rifling, chamber, muzzle threads, and crown to whatever spec the build calls for.

That flexibility is really the point of buying a Geissele barrel blank instead of a finished one. It arrives without rifling or finished threads, which means the twist rate gets selected when the barrel is finished rather than showing up fixed out of the box. For most 6.5mm builds, something in the 1:8.5 to 1:9 range tends to be the sweet spot — stable enough for lighter 120–130 grain bullets, but still capable of stabilizing the heavier 140–147 grain projectiles long-range 6.5mm shooters tend to favor. Estimated weight before machining runs roughly 4.5 to 6.5 lb, though the final number depends entirely on how the barrel gets finished and contoured downstream.

Whether the end goal is a precision rig, a competition build, or a dedicated hunting rifle, this 6.5mm barrel blank gives a builder a high-quality, adaptable starting point rather than locking in decisions before the project even begins.
