Sig Sauer M400 Tread AR15 5.56mm MLOK Semi-Automatic Rifle - RM400-16B-TRD

The M400 TREAD from Sig Sauer is a premium entry-level rifle, accompanied by a full-line of TREAD branded accessories that gives the consumer the freedom to grow. This premium rifle, at a moderate price point, is packed with innovation and flexibility, and doesn't sacrifice the quality demand from Sig.

This base model is loaded with features which would be considered costly upgrades on comparable models. 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.

Want to mount an optic? No problem! The TREAD is an optics ready, aluminum frame rifle. Other features include a single-stage polished/hard-coat trigger, ambidextrous controls, a Magpul™ SL-K 6 position telescoping stock, and a mid-length gas system. 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 Sig's entire TREAD brand can best be defined as the new face of freedom.
