M14 upgrade possible?

Well i am going to be buying a TSD M14 "Sniper Rifle" and i am wondering if i can upgrade it with a different spring. I just don't want my sears to snap after a couple shots. Please post some upgrades to prevent this problem.


Evike.com - PRESALE | Evike.com - (Pre-order ETA 3/10/2009) SYSTEMA M140 Taper Irregular-Pitch Spring (450~500 F.P.S.) |

P.S. I know, M14 is horribly crappy and i should go with the JG BAR, but i am on a budget.

All I did to mine was install an M120 spring,if you go higher than that you will need other upgrades like gears etc..M120 is all thats really needed though..

what FPS do you get now?

Yeh an M140 is quite alot, an M130 would be alright if your gearbox is in good condition, and metal gears, bushings you should be fine
