The bumpski will have the ability to be attached to different firearms simply by purchasing a different attachment bar. That is right. You simply remove the bottom half of the bumpski, purchase a different attachment for your SKS, Mini-14, or AR-15 and you do not have to buy a new stock time after time.
Great way to make an affordable way to have a bump fire stock for several firearms without having to disassemble your firearm. Simply pull down on the selector pin, slip off the bottom half of your bumpski, slip back on to your attachment bar on a different firearm.
