Sig Sauer M400 Tread 5.56 NATO/.223 Rem Features

The Sig Sauer M400 Tread is a no compromise AR style rifle with all the features you could want in a general purpose carbine. They start with an aluminum receiver set with a durable and scratch resistant hard coat anodized finish, and add ambidextrous controls to accomodate left handed shooters and make manipulations from the support shoulder a breeze. The upper is mated to a 16-inch stainless steel barrel with a 1:8 twist to stabilize a host of bullet weights, and the mid length gas system is optimized for the barrel length, providing reduced wear and recoil with superb reliability. To further reduce recoil the muzzle is fitted with 3 chamber muzzle brake that fights muzzle climb and keeps you on target during rapid fire. Surrounding the barrel is a free-floated M-Lok compatible handguard, that allows the quick and easy mounting of accessories, and increases accuracy. To help you get the most out of that accuracy the single stage trigger is polished and has a hard coat finish to decrease friction and give you a smoother pull with mil-spec reliability. Whether you’re looking for a home defense, competition or duty rifle the M400 Tread has the features you want, from a name you can trust.
