Hello everyone. New the the forum. I recently got back into paintball. Havent played in about a year. Back when i played alot i was using a stingray II. Well now I have a Spyder Victor II. Not the best one, but it serves its purpose good. well i recently started modding the gun. I put an e-marker trigger on, Progressive 14" barrel, Gunhead M-4 Stock, and a VL Quantum hopper. Well I came across one big problem. I am chopping balls like crazy. I usually shoot with semi auto, but i like to use the 3 round burst. and it is really bad on full auto, but even on semi auto it was chopping them. So I figured I should get a new bolt. My only problem, is i never got this deep into the guns before and I dont know a good one to get. Also anything else to help against chopping balls. I was using PMI balls, not the best but I know they arent that bad either. Thanks guys for any help.
