    Introducing SIG SAUER's newest addition to the TREAD series: the M400 Predator.

    Since SIG SAUER launched their TREAD series in 2018, TFB has brought you news coverage and reviews on this AR lineup. From their original 16″ 5.56 M400 model, to the 11.5″ pistol variant, to the 7.62 upsize in the 716i model, to the enhanced Coil version, the TREAD lineup has typically been well received. In general, they have been assessed as offering good value and performance for the price point, for those who can’t/don’t want to shell out bigger bucks and just need a straightforward AR on the more wallet-friendly end of the cost spectrum. SIG is now further expanding the lineup to include a specialized variant optimized for hunting predator animals. Meet the new SIG SAUER TREAD Predator, announced with the following March 29th 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.

    It will be interesting to see how the market receives this new version’s departures from prior models. In particular, some features that readily stand out are the handguard eschewing a traditional Picatinny top rail, and the stock’s precision-style adjustability. Though an official MSRP isn’t yet listed, it’s likely a pretty safe guess that pricing will end up reasonably close to the range of existing 5.56 baseline models, perhaps slightly more due to the development of specialized components.

    What do you think, readers? Will this gun be a hit for culling ecosystem- and agriculture-damaging animals like coyotes, bobcats, hogs, and more? Does this rifle’s configuration fit your needs for varmint management, or is there anything you’d change? Let us know in the comments below! See you at the range.
