SIG SAUER, Inc. is pleased to introduce the M400 TREAD COIL to the expanding line of TREAD products. The M400 TREAD COIL is an enhanced version of the popular M400 TREAD Rifle with the most popular TREAD branded accessories including the ROMEO5 TREAD Red Dot sight, match trigger, lightweight handguard, and vertical foregrip that come factory installed.

“The hallmark of the TREAD brand is combining innovation with value and offering consumers premium SIG SAUER products at an extremely affordable price point. Since its introduction, the demand for the TREAD brand has been phenomenal, and based on the popularity in the market, we have grown the brand from the base M400 TREAD rifle to include the 11” TREAD Pistol, 716i TREAD, and now the M400 TREAD COIL,” said Tom Taylor Chief Marketing Officer, and Executive Vice President, Commercial Sales. “Just like its predecessors, the M400 TREAD COIL combines innovation and value. This rifle is unique because it comes with a factory-installed red dot optic, making it ready to go right out of the box, along with other popular features that until now, were only available through an accessory purchase. The M400 TREAD COIL delivers the freedom to have an enhanced TREAD rifle right from the store with a very advantageous price that makes this an exceptional value to the consumer.”
