I have a practically new 28 NOSLER barrel with a 4 port brake for sale. $350 OBO
It was on a Remington 700 long action.
Bartlein 27" light Palma contour stainless barrel, 29" with the brake
4 port muzzle brake
Cerakoted Patriot Brown
I put 1 box of factory ammo through it to get it broken in before I got a smoking deal on a Proof Research barrel and swapped them. It was shooting the factory ammo at .5MOA
