Ballistic Advantage proudly produces quality AR barrels that exceed very stringent demands. Their AR-15 barrels surpass the competition in precision and aesthetics. For barrels that delivers round after round consistently and accurately, choose Ballistic Advantage.

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.

NOTE: Features a longer .750” profile necessary for proper installation of the OPS Inc 12th model collar and suppressor.

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.
