Geissele Automatics Geissele 6mm #4 Hunter Cut Rifle Barrel Blank 30-1313-2600-243-075-01-C

The Geissele 6mm #4 Hunter Cut Rifle Barrel Blank is a precision pre‑contoured barrel blank intended for custom rifle builds in 6mm (.243) calibers. With an overall blank length of 26.00 inches and a #4 Hunter Cut profile, this USA‑made barrel blank provides the raw material a gunsmith needs to finish the barrel exactly to your performance goals. Because it is supplied unrifled and unthreaded, twist rate, chamber, and muzzle threading are custom‑cut during gunsmith finishing. For general 6mm performance, a 1:7.5 twist is typically chosen to stabilize a wide range of bullet weights from hunting to long‑range match loads. Estimated blank weight before machining is roughly 3.8–5.0 lb, though final weight and balance depend on how the barrel is finished. This blank offers flexibility and high‑quality steel for precision‑oriented hunting, tactical, or competition rifle projects.
