Well I have had a B2K4 w/ pds for awhile now so I figured I would write a review. I had problems for it when I first purchased everything I needed to get the gun shooting. The only problem I had was the gauge starting sticking, so I bought a new one (the stock one is huge anyways). The rest of the problems were with my drop which had nothing to do with the gun itself since I bought it separately. Once I got the problems fixed, I had a decent shooting mid-end gun. My setup is a
