Full-optional and enhanced: here comes the SIG Sauer M400 TREAD COIL rifle

SIG Sauer welcomes a new member in its TREAD family, the M400 TREAD COIL. Chambered in 5.56 NATO, this enhanced version of the popular M400 TREAD Rifle sports the most popular TREAD branded accessories like the ROMEO5 TREAD Red Dot sight, match trigger, lightweight handguard, and vertical foregrip – all these come factory installed. The price, also including one 30-round magazine, is 1099.99 USD.

The M400 Tread rifle was introduced a couple of years ago as a no-compromise, high-quality premium rifle, just with an affordable price tag: “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. With its factory-installed red dot optic, the new rifle is actually “ready to go right out of the box”, according to the manufacturer.
