Sig Sauer MCX Spear LT 7.62x39mm 16" Rifle 28+1 Coyote

The Sig Sauer MCX Spear LT delivers proven piston-driven reliability in the versatile 7.62x39mm cartridge, combining modern engineering with battle-tested performance. This 16-inch barrel configuration provides optimal velocity while maintaining maneuverability in close quarters.

What Makes This Different

Built on Sig's advanced MCX platform, this rifle features a short-stroke piston system that runs cleaner and cooler than direct impingement alternatives. The adjustable gas block allows fine-tuning for various ammunition weights and suppressor use. The monolithic upper receiver provides a rigid platform for optics while the free-floating handguard ensures consistent accuracy shot after shot.
