Geissele 6.5mm G-Strat Cut Rifle Barrel Blank 27" Unrifled

A pre-finished barrel means someone else already made the calls on twist, chambering, and threading. The Geissele 6.5mm G-Strat Cut Rifle Barrel Blank 30-1313-2700-264-075-01-A skips that entirely, giving a gunsmith a precision machined rifle barrel blank with an overall length of 27.00 inches and a G-Strat cut profile, built specifically for custom projects chambered in 6.5mm (.264). It's unfinished by design — the raw material needed to cut the chamber, rifling, muzzle threads, and final crown to exact specifications, rather than a barrel that's already locked into someone else's decisions. That open-ended approach is the whole reason to buy a Geissele 6.5mm barrel blank instead of a finished one. Since it's supplied unrifled and unthreaded, the twist rate isn't baked in — it gets selected when the barrel is finished. For most modern 6.5mm applications, a 1:8.5 to 1:9 twist range tends to be the go-to recommendation, covering both match-grade competition bullets and heavier hunting projectiles without forcing a compromise. Estimated pre-machining weight lands around 4.5 to 6.5 lb, though the final number depends on how the barrel ultimately gets cut and contoured. Built from high-quality barrel steel in the USA, this Geissele barrel blank offers the kind of flexibility a finished product simply can't. Whether the goal is a precision competition rig, a hunting rifle tuned for a specific bullet weight, or a long-range build chasing exact performance numbers, this barrel blank gives a builder premium material and full control over how the final barrel turns out.
