SIG SAUER Introduces the “New Face of Freedom”: The M400 TREAD Rifle Featuring a Full Line of Accessories

Newington, N.H.-(Ammoland.com)- Today, SIG SAUER, Inc. introduced the M400 TREAD, a premium entry-level rifle, accompanied by a full-line of TREAD branded accessories that gives the consumer the freedom to grow.

“SIG SAUER has created a premium rifle, at a moderate price point, that is packed with innovation and flexibility, and does not sacrifice the quality that our consumers demand from SIG,” began Tom Taylor, Chief Marketing Officer and Executive Vice President SIG SAUER, Inc. “The base model of the TREAD is loaded with features that would be considered costly upgrades from our competitors base model. At this price point, most rifles are equipped with a barrel mounted sight post that blocks your field of view when using optics. Right out of the box, the TREAD features a factory-installed, aluminum, free floating M-LOK handguard for improved accuracy, and can be easily removed with two hex screws to change out to the TREAD accessory option.”

With this launch, we have created a full line of TREAD branded accessories that gives our consumers the freedom to grow, and customize their TREAD rifle. The TREAD accessories are premium interchangeable parts that require no specialty tools or armorer training, and are available for purchase with the TREAD rifle in stores today,” continued Taylor. “This rifle, combined with the accessories, both premium SIG SAUER products offered at a budget-friendly price, will set a new standard for the industry, and our entire TREAD brand can best be defined as the new face of freedom.”

    1. Looks like a nice rifle. Free float, slim m lock handguards, red dot, 1 in 8 twist, flip up sights, ambi controls, upgraded trigger. A midlevel price for a rifle with a lot of upgrades already on it.
      I want one!
      To TNoebel,
      Why would you want 3 different length handguards for the same rifle?
      You save $150 by just getting the length you want in the first place.

    2. I am sure that this is a very nice rifle but Sig should be sued for the takedown lever on the P320. Terrible design.

      1. First and foremost, the looks and features of the new rifle make it one worth considering in a pretty crowded field. I hope they offer the full kit in case like the pic at the top of the article. Be interesting to see the in-store price points.

        As to the P320 takedown lever, I have found mine to be both easy to manipulate and unobtrusive. Further, it is not difficult to remove and reinstall when accessing/removing/installing the FCU. What has your experience been?

        1. Extremely difficult to turn and there are many other owners with the same problem. Have to use a hammer and a wood dowel to move it. Sig has been no help. Many owners are considering a class action lawsuit against Sig.

          1. A class action lawsuit because you have a little bit of trouble manipulating part of a firearm? Get the hell out of here haha. I would say good luck, but you’re FOS from the start so its not a valid wish.
