I have 2 factory take off barrels that I used the actions for custom builds. 1. 24" barrel heavy varmint. 1and 11.25 twist. Less than 500 rounds. Took it off my 5r mil-spec special. Barrel is stainless and no flutes or threads. 308 caliber. 2. 26" sendero. 1and 10 twist, fluted, 300 rum. 247 rounds. Both guns shoot very well with hand loads. 308 was turned into a fast twist 243 and the 300 had a Tank barrel put on. 200$ shipped each. Or 350$ for both. Prefer MOs.
