McMillan Tac-338
A bolt-action precision rifle chambered in .338 Lapua Magnum.
The McMillan TAC-338 is a bolt-action rifle built by McMillan Firearms for long-range precision work, firing the .338 Lapua Magnum cartridge. It sees regular use in military, law enforcement, and competitive shooting due to its accuracy and dependability at extreme distances.
The rifle comes with a 27-inch medium-heavy barrel that has a twist rate of 1:9.35 inches, designed to stabilize heavy .338 Lapua Magnum bullets. A muzzle brake is fitted to cut recoil and help the shooter maintain control during quick follow-up shots. The stock is made from synthetic or fiberglass, depending on the version, and includes an adjustable cheekpiece for comfort, flush-mounted swivel cups for sling attachments, and a spacer system to change the length of pull. Other features include an adjustable trigger where the pull weight can be set by the user, and a detachable box magazine that holds five rounds. The receiver is drilled and tapped so optics can be mounted.
The TAC-338 has been adopted by the U.S. Navy Special Warfare and by Israeli special forces. Its .338 Lapua Magnum chambering lets it effectively engage targets past 1,500 meters, making it suitable for counter-sniper and anti-materiel roles. Because the rifle is ITAR-restricted, international sales require approval from the U.S. State Department.
