Sig Sauer MCX-SPEAR 6.8X51

In 2022, a historical announcement was made to officially select the SIG SAUER MCX-SPEAR as the XM7 service rifle by the U.S. Army. In combination with the groundbreaking 6.8×51 hybrid ammunition, the SIG SAUER MCX-SPEAR has become the pinnacle by which rifle capabilities will be judged.

Capable of muzzle velocities in excess of 3000FPS with a 113gr bullet out of a 16”barrel, the SIG SAUER MCX-SPEAR rifle is achieving the Army’s goal of advanced performance while also exceeding the requirements for durability. Now for the first time, this technology will be available to the U.S. civilian market with the MCX-SPEAR rifle chambered in6.8×51 along with a family of Hybrid Ammunition from SIG SAUER. The SIG SAUER MCX-SPEAR platform also offers a new level of modularity, allowing for caliber conversion between 6.8×51, 7.62×51 and 6.5 Creedmoor and 13” or 16” barrel length options. In addition, the MCX-SPEAR features a non-reciprocating side charging handle, a rear charging handle, fully ambidextrous controls, a 2-Stage Matchlite Duo Trigger and a free-floating M-LOK™ handguard.

For the first time in more than 30 years a new rifle has brought an entirely new level of performance and reliability to the U.S. Army, and is now ushering in a changing of the guard.
