Steviewev23 Posted March 13, 2015 Posted March 13, 2015 I've run my VFC M4es standard for a while now (apart from a firefly bucking) and looking to upgrade it now, I'm looking at buying a set of Lonex 13:1 gears, M120 or M110 spring and a Lonex Titan A2 and I'm going to be shimming the new gears and doing AOE. Would this be a good setup? What else should I look into upgrading whilst I'm in there? Thanks, Steve
n1ckh Posted March 13, 2015 Posted March 13, 2015 I would suggest new piston, piston head, cylinder head & nozzle (double O-ring) I upgraded mine with all SHS and had to downgrade to an M90 spring (was shooting between 360 & 380fps) also did AOE at the same time
