Hey I wanted to upgrade my CA M15A4 Tactical carbine so that it shoots really fast but still has a good amount of FPS like 340-350.
[quote="Steele"]Thats a hot weapon,Your safety should be on at all times on base.[/quote]
take it back to AEX and have them "fix" the air leak, find out what your gun is shooting w/ the 120 spring go from there FPS wise... if you want a faster rate of fire lower the fps and look into high speed gears and/or high voltage batteries, possibilities such as 10.8v ni-cad/ni-mh or 11.1 li-poly/ion, all dependant on how high ROF you are looking for.
