Geissele 6mm Straight Cut Rifle Barrel Blank 30-1313-2700-243-075-01-Z

The Geissele 6mm Straight Cut Rifle Barrel Blank is a precision barrel blank engineered as the foundation for custom rifle builds chambered in 6mm (.243). With a 27.00‑inch straight cut profile and high‑quality barrel steel, this blank provides raw material for a gunsmith to cut the rifling, chamber, muzzle threads, and crown exactly to your specifications. Because the blank is supplied unrifled and unthreaded, the twist rate is not set — the typical recommended twist for balanced performance with a broad range of 6mm bullets is 1:7.5, which stabilizes both medium‑weight match bullets and heavier long‑range projectiles. Estimated pre‑machining weight is roughly 4.0–6.0 lb, though final mass depends on how your gunsmith finishes the barrel. Ideal for precision, hunting, or long‑range 6mm builds where performance and custom chambering matter, this Geissele barrel blank is a flexible platform for tailored rifle construction.
