Strike First, Strike Hard, and Strike Fast With the New SIG Sauer MPX K That Has Been Redesigned for 2019

The SIG Sauer MPX K has been redesigned and features an all new release in 2019. Originally this platform was specially designed to meet the ever changing needs of the special operations community. Civilian and Law Enforcement officials quickly realized the benefit of the MPX platform and it’s adoption to a broader market has been swift. The MPX still runs on a gas piston system which runs clean and reliably. Additionally this unit is modular allowing for multiple hand guard and barrel lengths and is ready to go for suppressor use. The K also features a M-LOK hand guard ultra fast Timney Trigger System and the new SIG PCB folding brace which allows the K to fold into an ultra-compact size and be operable in the folded position. What more could you want out of an ultra modular sub gun platform, so look no further then the MPX K from SIG Sauer.
