The anti-materiel rifle is a magazine-fed, bolt-action .50 caliber rifle that is designed for use against military targets and equipment (or "materiel" in military jargon). The GRA variant is similar in design principle to that of a sniper rifle, delivering a high-powered shot at long distances with great accuracy. It is specially chambered with a larger caliber for hardened targets, and as such has extremely high damage and low weapons spread, and is scoped with a magnification level 3.13x. The damage benefits of the rifle are offset by the fact that it is bolt-action, greatly lowering the rate of fire and resulting in a low damage-per-second; the weapon itself without modifications weighs in at 20 pounds, making it one of the heaviest shoulder-fired weapons in the game. The gun's recoil is extreme, causing the shot to push the player back a few inches.
If the Trigger Discipline trait is taken, the rifle's custom bolt cancels out the decreased firing speed penalty.
Even when upgraded with the suppressor modification, the rifle is still not technically silenced. Missing a target will still sometimes alert enemies to the player's presence, unlike other rifles, such as Christine's CoS silencer rifle.
Utilizing the Heavyweight perk and the carbon fiber parts modification, this weapon's weight can be reduced to 6.5 pounds, making it one pound heavier than a varmint rifle, and two pounds lighter than a service rifle. This will significantly increase the weapon's desirability for players who wish to travel light.
When firing this weapon in third person, the recoil is strong enough to blast the Courier back a step.
