30 inch Stainless Rock 1-8.7 twist ABS carbon fiber wrapped barrel chambered in .270AM fitted for Borden Timberline action (Remington). Threaded for brake. Here is the full disclosure: Barrel appears perfect when veiwed through bore scope. Cold barrel grouped sub-moa. As barrel heats up the group size increases. Barrel cools back off and we're back to sub-moa. Barrel test fired only for groups. Seems to me for hunting purposes (cold barrel) this would be fine but you'll have to make up your own mind. My rifle is now a .338 Edge as the wait time on an ABS replacement was to long to endure again. This barrel would cost well over a grand without machining-MAKE OFFER.
