these were tried on different markers in the past. several types of smart parts barrels ( all american venturi ) J&J brass taso SS . Most of these were on my old mag . Got a armson and never looked back. played with it for two seasons.
Phantom pump with armson barrel , taso expansion chamber,& bottom line, Getting JT 5.0 this week.
Proball is good , also been trying power ball and it seem s to drive tacks also.
What every Pb player is looking for range and accuracy. Not quite understanding the whole quiet thing.
Nothing really It definatly barks , some people dont like noisy guns. I personally like it.
Thus far I have yet to find a barrel that is as good. I personally don't mind the noise it makes it can be very intimidating . Indoor with one is a blast. TEn is the best that they allow but in my book it rates higher than that. I recomend this barrel to everyone. I will be getting one for the JT as soon as i can.
