Sig Sauer recently introduced the M400 which features a gas impingement system carbine. Based on market needs for a reliable, less expensive alternative to the 516’s piston operating system. Both the 516 and M400 feature Sig Sauer’s ambidextrous lower receiver.

Here you can see the 516 paired with the Elite suppressor. They have measured less than 100 db with this can. An interesting feature of the 516, is that you can dial the gas down to the point that it can be fired without cycling the bolt, further reducing the audible signature by 2-3 db. Of course, the biggest downside to suppressed 5.56 is the lack of subsonic ammo.
