This Butt includes all the upgrades to date. Tool and adapter included! 

Having an extra butt for your Leshiy 2 not only means that you’ll always have a backup at hand, but also that if you take it with you during your shooting sessions, you can keep the fun going on well after emptying the first tank…

If you like to switch between power settings or like to change calibers rather often then the upside will be rather obvious to you. Whatever you choose, we’re pretty sure that having two butts will enhance your shooting experience!
