I’ve got a 7 twist, 26 inch, M24 contour, 6 BRA barrel prefit for Impact 737. It’s Cerakoted graphite black with some slight scuff marks from transport and my stupid barrel vise. It’s a Rock Creek blank chambered by CJS Precision. I think I put about 15 rounds down it, it shoots great, I just ended up getting a bunch of Dasher brass and decided to use that for a while. $425 shipped CONUS with an Area 419 Hellfire adaptor on it (no brake included). Can update later with photos if needed.
