I assume that's you in the picture with your weapon.
yes. i just bought a new barrel. went to get the paintball gun and found my barrel and O2 were missing. found a longer barrel for 25$, the stock is about 6inch and the one i bought is 14inch [increases Speed and accuracy of the projectile]. the O2 containers were over 120$ at the place i bought the barrel so i held off, wound up finding the O2 without having to buy a new one anyways.
