also not a bad idea to get a good recoil system in place on it so you’re not sore after using it awhile.
woops, wondering what a recoil system is... (tia for any clarifications)
One way or the other, they are probably not going to have the opportunity to use it that many times. If it is an unfavorable result, a sore shoulder is the least of the problems. Likely to be taken out, overrun, or run off the survivors before you get off more than a handful of shots.
