Back in 2018, SIG SAUER released their Tread Series to the firearms market. Since then the Tread series has been well received by the firearms community. The series features the original 16” M400 model, 11.5” pistol, and the 716i model shooting .308. Now, SIG has up the ante with the new SIG SAUER Tread Predator. SIG optimized this rifle for shooters hunting predator animals. The new rifle was announced by SIG SAUER on March 29th with a press release. Below, is the press from SIG SAUER on the new Tread Predator.

Press Release


NEWINGTON, N.H., (March 29, 2021) – SIG SAUER, Inc. is pleased to introduce the SIG M400 TREAD PREDATOR, the newest addition to the SIG hunting rifle line-up.

“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, Chief Marketing Officer 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.”

The M400 TREAD PREDATOR is an aluminum frame rifle with a Cerakote Elite Jungle finish, a precision style adjustable stock that maintains a lightweight design, a 16” stainless steel threaded barrel with thread protector to eliminate snag points that can be removed to add a suppressor, a lightened free-float M-LOK™ 15” PREDATOR handguard, a hardened polished trigger, and ambidextrous controls.

SIG SAUER has not released a price point for the new Tread Predator but, I imagine it will be in the ballpark as its predecessors. Potentially, a little more since the rifle has some specialized components.
