Sig Sauer Has 2 New M400 Rifles

The New Hampshire-based small arms giant has turned its eyes to its direct impingement 5.56 NATO AR-15 beanstalk and shook out a pair of new M400 series rifles. This includes the M400 SDI X-SERIES and M400 Tread Predator 2.0.

If the “X-SERIES” sound familiar, Sig uses that name for its optimized P320 pistols that include lightening cuts and high-speed features. To live up to that, the M400 SDI X-SERIES includes a flat-blade 2-stage trigger, lightened receivers, and a 16-inch 1:7 barrel.
