Geissele 7mm #4 Hunter Cut Rifle Barrel Blank 30-1313-2600-308-100-01-C

A finished barrel locks in decisions someone else already made. The Geissele 7mm #4 Hunter Cut Rifle Barrel Blank 30-1313-2600-308-100-01-C skips that trade-off entirely, handing a gunsmith a precision pre-contoured barrel blank chambered in 7mm (.284) and letting the builder make the calls instead. At 26.00 inches with a #4 Hunter Cut profile, this raw blank gives a qualified smith everything needed to cut the chamber, rifling twist, muzzle threads, and crown to exact specifications.

That's really the appeal of a Geissele barrel in blank form rather than pre-finished. It arrives unrifled and unthreaded, so the twist rate gets determined at the finishing stage instead of being fixed at the factory. For most versatile 7mm work, a 1:8 twist tends to be the recommendation — wide enough to stabilize a broad range of bullet weights, whether the build leans toward lighter, flatter-shooting loads or heavier long-range projectiles. Estimated pre-machining weight comes in around 4.0 to 6.0 lb, though the final weight and balance depend entirely on how the barrel gets cut and contoured from there.

The #4 Hunter profile signals where this blank is headed — a contour built for hunting rifles that still need to hold accuracy at distance, not just shed weight for the sake of it. Made in the USA from high-quality barrel steel, this 7mm barrel blank is built for precision hunting, competition, or long-range projects where the whole point is dialing in specs a factory barrel simply can't offer.
