SP-1: Carbine Spring and Buffer Kit


The Vltor SP-1 Carbine Spring and Buffer Kit is an exceptional choice for replacing existing parts or for a new build of a carbine rifle. The parts are manufactured to ensure accuracy and reliability in the weapon system. This kit comes with a standard 3oz carbine buffer (3.25″ OAL), standard carbine spring, Vltor lockplate, and castle nut.

***These components are standard carbine components. These are NOT components from our A5 buffer system.
