VLTOR WEAPON SYSTEMS introduces the Modular Firearm Buttstock, known as the Modstock. The Modstock is available in two lengths for the A-15/EM-16 - rifle and collapsible carbine series. The Modstock was developed to be a "chassis or platform" for future mounting possibilities. Also, the Modstock offers a variety of sling mounting options by conventional means or with an ambidextrous quick detachable sling swivel.


Unlike any other stocks available the Rifle Modstock fits both the standard A-15/EM-16A2 rifle receiver extension and the CAR-15/AP4 carbine collapsible-stock receiver extension. So, now you can use that match-grade upper-receiver assembly on your collapsible-stock lower, without sacrificing comfort.


The Modstock system comes complete, including all mounting hardware, quick detachable sling swivel and the Vltor's mountable accessories, such as Accessory Compartments, with the inner dimensions accepting a 3-volt lithium battery.
