New Hampshire-based Sig Sauer on Monday announced the latest expansion of its Tread M400 series, the 5.56 NATO caliber Predator. 

As the name would imply, the lightweight semi-auto platform is intended for use by sportsmen involved in predator hunting. In line with that thinking, it has a Cerakote Elite Jungle finish, a precision-style adjustable stock, 16-inch stainless steel threaded barrel under a lightened free-float M-LOK handguard, ambi controls, and a hardened polished trigger.

"The M400 Tread Predator combines the popular features of the Tread series of rifles, including ambi-controls and easily interchangeable Tread branded accessories, with new attributes that optimize the M400 platform for hunters," said Tom Taylor, Sig's CMO and executive vice president, commercial sales. "The new features include a stock that easily adjusts for both length of pull, and comb height so the hunter can get properly aligned no matter the circumstance, QD mounts to attach a sling for easy carry, a new Tread handguard system with a flat surface bottom, and a Cerakote Elite Jungle finish to minimize visibility and protect the rifle in woods and brush environments."

When it comes to specs, the 1:8 twist 16-inch barrel stretches the rifle to 35.5-inches overall. Weight is 7.5 pounds. (Photo: Sig Sauer)

The carbine uses a direct impingement gas system and ships with a 5-round polymer mag. However, it accepts all standard AR pattern 5.56 NATO magazines as well as Sig's own well-stocked line of Tread- branded accessories.
