SIG Sauer MCX Spear 6.8x51mm 16" Coyote - Rifle - 1x 20rd Mag

Over 3,000 fps from a 16-inch barrel — now available to U.S. civilian shooters. The SIG Sauer MCX Spear 6.8x51mm Rifle brings the Army's Next Generation Squad Weapon platform to the civilian market, pairing advanced 6.8x51mm ballistic performance with a non-reciprocating charging handle system, 2-Stage Match Duo Trigger, and free-floating M-LOK handguard in a Coyote-anodized folding-stock package.

The SIG Sauer MCX Spear 6.8x51mm Rifle is a short-stroke piston-operated semi-automatic rifle chambered in 6.8x51mm, based on the U.S. Army's NGSW M7 platform, featuring a 16-inch cold hammer-forged threaded barrel, 2-stage curved match trigger, folding/telescoping Magpul SL-M stock, and fully ambidextrous controls in a Coyote anodized finish.

Four features define the MCX Spear's performance advantage. The 6.8x51mm cartridge delivers muzzle velocities exceeding 3,000 fps from the 16-inch barrel with a 113-grain bullet, providing a significant terminal performance and barrier penetration advantage over 5.56 NATO at the same barrel length. The short-stroke piston operating system runs cleaner and cooler than direct impingement, reducing fouling accumulation in the bolt carrier group and providing greater tolerance to environmental conditions and ammunition variation. The 2-position adjustable gas valve with M-LOK handguard enables a dedicated suppressed setting for consistent cycling when a suppressor is attached, without additional modification. Non-reciprocating side and rear charging handles combined with fully ambidextrous controls — including bolt catch and bolt release — accommodate left and right-handed shooters in any shooting position.

Compatible with AR-10-type 20-round steel magazines. 5/8x24 threaded barrel. Overall length: 34.8 inches extended, 28.1 inches folded. Weight: 9.2 lbs.

Coyote anodized receiver. Cold hammer-forged 16-inch barrel. 1:7 twist. CLUTCH-LOCK QD flash hider. 2-stage curved match trigger. AR-compatible reduced angle grip.
