m14 gearbox

http://www.airsoftpost.com/complete-gearbox-echo-p-28793.html would this be able to hold a PDI 190 or 210 spring? i'm gonna make a m14 as my next weapon insted of an m4

NO. a 190 spring will tear that thing to shreads.......wait aint PDI 190 sniper rifle springs anyway?

but the biggest you could run in that for a would be....the stock spring..you would have to get a tuneup kit for a TM M14 and if is a CYMA M14 it will work...my friend put one in with no flaws

since i'm getting a CYMA i could get a powa spring?

well the strongest spring tune-up kit(wel you have to get this because an M120 spring will tear a CYMA gear box to shreads) i have seen for an M14 was an M120

so wat do i need or what do i do...?.....how

well look on evike or ASGI (don't remember witch..think it was ASGI0 for n M14...just serch M14 tune up or somthing like that and you will find it. and if you going to DMR it then i suggest a TBB (a 6.03)

thanks
