What upgrades would you give a TM M14 if you had 50 dollars or so,(I can scrounge up mroe money if what you recommend is a little over my budget by 50 or so dollars)? Strictly to improve accuarcy,range, and consistency? Since it has 280 fps I figured I'd upgrade the fps to a spring that would be shooting 380 fps. What's the max fps the gun can handle? I'm a bit stuck inbetween either a m`6, or a m14 so sorry for asking questions about a different type of gun.
