This is a McGowen custom barrel chambered in 6.5x47 Lapua and has an 8.5 twist. It is for a savage target action and is finished at 17" It's a savage varmit contour and is .8 at the muzzle. It does not have a crown since I was going to attach a brake. This was going to be for a long range handgun. It is brand new never been used. Keep in mind the target action is a large shank (1.125" diameter) so this barrel is slightly larger in diameter than the standard barrels for the standard actions. I paid $160.00 for the barrel so I'm open for offers.
