Geissele Automatics Geissele 7mm MTU Cut Rifle Barrel Blank 30-1313-2700-308-100-01-B

The MTU profile has a reputation in precision circles for a reason — it's a contour built around stiffness and consistency rather than shaving weight at the expense of accuracy. The Geissele 7mm MTU Cut Rifle Barrel Blank 30-1313-2700-308-100-01-B brings that profile to a rifle barrel blank chambered in 7mm (.284), giving a gunsmith 27.00 inches of raw steel to work with rather than a barrel already committed to someone else's specs. Like the rest of Geissele's blank lineup, this one is supplied unrifled and unthreaded, so the rifling, chamber, muzzle threading, and crown all get cut during finishing. That leaves the twist rate genuinely open until a smith sets it — for most 7mm work, a 1:8 finished twist is the typical recommendation, since it balances performance across everything from medium-weight hunting loads to the heavier long-range projectiles 7mm is known for. Estimated pre-machining weight runs roughly 4.5 to 6.5 lb, though the final weight and balance come down to how the barrel gets contoured downstream. What sets the MTU cut apart from Geissele's other profiles is that stiffer, more substantial build — the kind of contour precision and tactical shooters tend to gravitate toward when barrel rigidity matters as much as the twist rate itself. Manufactured in the USA from high-quality barrel steel, this 7mm barrel blank is built as a serious foundation for projects where the finished barrel needs to hold up under demanding use, not just look good on a spec sheet. Whether the end goal is a precision competition build, a tactical rifle, or a long-range project chasing specific performance numbers, this Geissele barrel blank gives a smith the material to get there on their own terms.
