As expected, it didn’t take long for the new SIG Sauer M400 Tread to build a warranted buzz. With plenty of “room to grow,” the offering marks SIG’s unique take on the concept of an entry-level rifle.

We got our first look at the M400 Tread at the 2018 Athlon Outdoors Rendezvous in Montana. Tactical-Life contributor Todd Burgreen was the first to take the M400 Tread out for a spin on the range.

“The SIG M400 Tread is a top choice for any AR connoisseur no matter if its your first rifle or 10th,” he said. “Performance combined with price — it can be found starting around $799 in stores — is the quickest way to appeal to the shooting public. The M400 Tread will have no problem proving its worth.

And an update for September 2019, SIG just unveiled its SIG M400 Tread Pistol. The pistol variant puts a rifle caliber and a 30+1 capacity into a compact package with a barrel length of just 11.5 inches.
