Sig Sauer M400 Tread Snakebite SE 5.56NATO 16″ 30 1

Sig Sauer M400 Tread Snakebite SE 5.56NATO 16″ 30 1

SIG SAUER first introduced their M400 series over a decade ago, with the initial version’s release in 2010. The M400 concept was meant to be SIG’s entry into the world of budget-friendly AR-15s. These guns differ from SIG’s pricier rifles like the MCX Virtus Patrol, which is a piston-driven platform, and fall more closely in line with the direct impingement operation that has become generally accepted as “standard” for ARs. Until recently, the series’ current models covered the basics: a regular 16″-barrelled rifle, an 11.5″ pistol, and an upscaled rifle variant that came with some factory upgrades, like an optic and flat trigger. There is also a large-frame cousin, the 716i Tread. This AR-10 shares most of its DNA with the above 5.56 models, but is chambered in 7.62 instead. Never a company to rest on its laurels, SIG is now expanding the M400 family with two new models announced in 2021: the Switchblade (to be covered soon) and the Predator, which I’ve spent the last few months getting to know.

The Predator model represents a bit of a departure from the M400 lineup’s extant variants. Whereas the other Tread guns all tend to provide what most shooters would commonly expect in modern AR-15s’ feature sets and configurations, the Predator prefers to buck some of those conventions. Although at its core, it’s still based on the ubiquitous 5.56/.223 gas-operated AR platform that so many of us have come to know and love, SIG has opted to eschew “standard” in some key areas. The most noticeable to me were two: the buttstock and handguard. Rather than the typical telescoping stock on a 6-position buffer tube, the Predator employs a stock system more akin to those often found in precision rifle chassis. Length of pull is adjusted by virtue of a retractable buttpad, and comb height can also be customized. As for the handguard, an atypical squared-off profile was chosen in an effort to maximize stability when resting the gun’s front end on a surface or tools like shooting sticks. The M-LOK fore-end also lacks any Picatinny rail sections, which are normally found running the full length (or at least having several slots toward the muzzle end) of the 12 o’clock top face of an AR’s handguard. The only pic rail segment is found on top of the upper receiver itself.
