Elts7 Posted January 15, 2017 Posted January 15, 2017 morning all. just looking for advice on what i van do to improve my stubby m4. 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?
Guest PT247 Posted January 15, 2017 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?
Guest PT247 Posted January 15, 2017 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
Elts7 Posted January 15, 2017 Author Posted January 15, 2017 thanks what hop style would you reccomend?
Guest PT247 Posted January 15, 2017 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.
Elts7 Posted January 15, 2017 Author 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?
Guest PT247 Posted January 15, 2017 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.
Elts7 Posted January 15, 2017 Author Posted January 15, 2017 im not making it longer but i cant find any 140mm barrels was looking at the pdi 6.05 and smallest i could see was 247mm
Guest PT247 Posted January 15, 2017 Posted January 15, 2017 http://www.x-fire.org/etop/05.html The 141mm barrel at the top of the list
