Dave Grimshaw, Rifle Product Manager for SIG Sauer, talks about the company’s SIG M400, at the 2011 NRA Annual Meetings and Exhibits in Pittsburgh.
The M400 is a direct gas impingement AR-style gun that Sig states uses many of the features from the Sig 516. (the 516 is a piston gun). The M400 uses a M-4 style stock, an A-2 style pistol grip and has a removable carry handle. The chrome-lined barrel has a 1:7 twist.
