SIG SAUER, INC. – M400 TREAK SNAKEBITE 5.56 | A Premium-Quality SIG Sauer AR-15 at a Price You Can Afford

SIG SAUER, INC. – M400 TREAK SNAKEBITE 5.56. Generally, when you consider SIG Sauer guns, you’re thinking about high-dollar weapons that run in elite circles. The SIG Sauer M400 Tread makes it possible to have all the luxury features found in a high-quality SIG Sauer rifle at a price you can afford, plus the Tread system this rifle is based on makes it simple to upgrade and swap out components, so you can make your rifle your own.

Each SIG Sauer M400 Tread is manufactured with a mid-length gas system that provides dependability while reducing extra wear on internal components from over-gassing.

An extra advantage of this setup is that it lessens recoil, so you’ll have a sweet-shooting rig. The direct-impingement action is based on a 7075 aluminum receiver set, which is finished with a hard coat anodized finish for durability. The rifle is furnished with a 16-inch barrel chambered in 5.56 NATO, and empty, it weighs in at 7 pounds. Each weapon arrives with a single 30-round magazine.
