SIG Sauer announces two new rifle optics and a new version of the M400 rifle: enter the Predator rifle, and the Romeo7s and Juliet3-Micro optics

In 2021 SIG Sauer will introduce many new products: here we present the latest addition to the M400 Tread series of rifles with the M400 Tread Predator, designed specifically for predator hunting and inclusive of feature changes to suit the needs of hunters; also, from SIG Sauer’s Electro-Optics Division, a complementary set of optics, the Romeo7s miniaturized red dot and Juliet3-Micro 3x compact magnifier, that can be used for hunting, professional and sports activities. 

SIG Sauer M400 Tread Predator hunting rifle

The M400 Tread Predator is a semiauto rifle chambered in .223/5.56 NATO, based on the proven Black Rifle/AR-15 pattern, with both aluminum upper flat top and lower receivers finished in Cerakote Elite Jungle color, and a precision style stock that is adjustable for comb height and length of pull while maintaining a lightweight design. The 16” stainless steel barrel features a crowned muzzle with a thread protector to eliminate snag points; the smooth handguard is a lightened free-float M-LOK 15” Predator proprietary part. Controls are ambidextrous and the trigger is hardened and polished. 

The M400 Tread Predator is built for accuracy. The M400 Tread Predator is compatible with all the available SIG Sauer TREAD accessories, including varying lengths of M-LOK Handguards, a 3-chamber compensator; an ambidextrous charging handle made of aircraft-grade aluminum; flip-up front and rear iron sights that are easy to install, adjustable, and deploy quickly; an M-LOK front sight adapter with co-witness height made of lightweight aluminum; and multiple configurations of M-LOK grip kits made of high-strength polymer.
