Guest PT247 Posted January 15, 2017 Share Posted January 15, 2017 Stick in a PDI 6.05 or Prometheus 6.03 barrel and try a Prowin hop unit. PTFE tape around the bucking to improve the airseal. What joules is it kicking out? Link to comment Share on other sites More sharing options...

Guest PT247 Posted January 15, 2017 Share Posted January 15, 2017 You are gonna want a bit more fps too then so a new spring once you have sorted out the airseal and barrel Link to comment Share on other sites More sharing options...
Elts7 Posted January 15, 2017 Author Share Posted January 15, 2017 thanks what hop style would you reccomend? Link to comment Share on other sites More sharing options...
Guest PT247 Posted January 15, 2017 Share Posted January 15, 2017 you mean like r-hop etc? I'd go with a flat hop, easier to set up than the r-hop and very similar results. Link to comment Share on other sites More sharing options...

Elts7 Posted January 15, 2017 Author Share Posted January 15, 2017 as the barrel in it is only 140 long would i be able to cut it down or would i get a longer one and add a silencer or something? Link to comment Share on other sites More sharing options...
Guest PT247 Posted January 15, 2017 Share Posted January 15, 2017 I thought you said you were happy with the size of the gun? Why shorten it or make it longer? the size is perfect in which is why i want upgrade it im finding the grouping and accuracy isnt great so im assuming i want to change the hop and possibly the unit? And as I said before, buy a better barrel: Stick in a PDI 6.05 or Prometheus 6.03 barrel and try a Prowin hop unit. PTFE tape around the bucking to improve the airseal.
