Sig M400 TREAD 5.56/.223, 16″ Barrel, SL-K Stock, Midnight Bronze, 30rd

We didn’t set out to make just any M4. Instead, we used the innovation, performance and attention to detail that defines other SIG rifles to evolve the platform. The result is the SIGM400, a superior system offering advanced features available right out of the box that were once only found on the after-market.Category : Rifles Centerfire TacticalAction : Semi-AutomaticCaliber : 223 Remington/5.56 NATOBarrel Length : 16″Capacity : 30+1Trigger : Single StageOAL : 30.8″Weight : 7 lbsStock Description : Magpul MOE SL-K BlackMetal Finish : Midnight Bronze Cerakote
