Geissele 6mm G-Strat Cut Rifle Barrel Blank 30-1313-2700-243-075-01-A

The Geissele 6mm G‑Strat Cut Rifle Barrel Blank is a precision‑machined barrel blank produced in the USA for custom rifle builds chambered in 6mm (.243). With a 27.00‑inch G‑Strat pre‑contoured profile, this blank gives a gunsmith the raw material needed to cut the chamber, rifling (twist rate), muzzle threads, and crown to your exact specifications. Because the blank arrives unrifled and unthreaded, the twist rate is determined during finishing — the typical recommended twist for all‑around 6mm performance is 1:7.5, which stabilizes a wide range of 6mm bullets from lightweight hunting bullets to heavy long‑range projectiles. Estimated pre‑machining weight is in the ~4.0–6.0 lb range, but the final weight depends on how the barrel is cut and contoured. Ideal for precision, hunting, or long‑range 6mm rifle projects, this barrel blank provides a flexible, high‑quality foundation for a custom barrel build.
