Please add to cart for your price$270.75
This premium barrel is chambered in 6.5 Grendel Type II. Machined from 416R stainless steel with a bead blasted finish, the barrel features a FailZero nickel boron coated extended M4 feed ramp extension.
Safety Note: Choosing 6.5 Grendel comes with an added complication. There are “Type I” and “Type II” bolt/barrel specifications out there, and you CAN NOT mix and match parts for each of them without risk of damage and/or injury. Type II is by far the most popular configuration, but pay attention to what you are buying! A Type I bolt won’t chamber rounds in a Type II barrel at all. Even worse, a Type II bolt mated to a Type I barrel will create excessive headspace and result in a rifle that is dangerous to fire.

Would buy again with no hesitation.

My barrel proved to be a tack driver. Sub moa @ 100 with hornady black factory ammo. Handloads produced .5 moa after testing. As always primary arms is outstanding.
