Sig Sauer Carbon Fiber Rifles in the SIG516 and SIGM400 platforms sport 12-inch free-float carbon fiber handguards and A1 length carbon fiber stocks, shedding weight without sacrificing strength.

While the upper and lower receivers are both aluminum, it is the handguard that is free-floated and made from carbon fiber, as is the stock. The rifle also features a four-position gas system and two-stage trigger.

Both the SIG516 and SIGM400 Carbon Fiber rifles come with a Lancer Systems polymer magazine and Sig Sauer flip-up, adjustable and lockable iron sights.
