CMI TRU-FLIGHT THUNDER PIG BARREL, AUTOCOCKER THREADS Autococker barrel that I cut down a bit and was experimenting with some apex ends but it didn’t work out perfectly. It should still work well as an acceptable autococker barrel for many newer paintball markers such as planet eclipse ego or empire axe. Straight “linear” rifled barrel designed to help the paintball have a spin free projection (which is a good thing for pointing at a paintball opponent so it doesn’t deviate) Porting holes on the barrel to help with quieter sound signature and accuracy. Bonus: Also included is a high quality lapco brand adapter, together they can be a nice tippmann a5/x7 barrel
