Caleb breaks down his LMT MARS-H .308 setup after putting roughly 500 rounds through it during a five-day Basic Sniper Course. From the 16-inch LMT barrel and Nightforce NX8 to the SureFire SOCOM suppressor, MDT bipod, SPUHR mount, Geissele trigger, and B5 Systems stock, this video covers the complete rifle setup and what worked during the course.
Chambered in .308 Winchester, this LMT MARS-H was built around a compact 16-inch barrel while still providing the capability Caleb needed to engage targets out to 500 yards. During the Basic Sniper Course, he fired approximately 500 rounds of Hornady 168-grain ELD Match and came away impressed with the rifle's performance.
Caleb walks through the rifle from muzzle to stock, explaining why he selected each component and what he learned after spending a week behind the gun.
