Designed for operators, by operators. The new Remington® Modular Sniper Rifle (MSR™) combines lethal accuracy at 1500 meters with a user adjustable folding stock, free-float handguard, and the potential to change barrel lengths and calibers within minutes at the user level from .338 Lapua Magnum to .338 Norma Magnum to .300 Winchester Magnum to 7.62mm NATO. This patent-pending system addresses long range and medium range performance needs of the modern battlefield in one package loaded with features designed to meet multiple emerging US armed forces requirements. The system features lightweight, efficient design and optimal material selection for corrosion resistance and strength. The MSR is mission-adaptable and can change the bolt face, barrel, and magazine to enable a smaller profile or different caliber. This system truly never has to leave the battlefield.
