Firstly make an intro. I have this kit and I would say that you should really upgrade the trigger. Especially if you want the gun to last. It is a surprisingly good kit. To behonest though for just a little more I would go over to xfire airsoft and buy a piston and metal spring guode there. I would also keep the spring that comes with the gun.that way you have better internals and you dont have to upgrade the gun's trigger yet.oldgreggtwo said:hey i was thinking of buying this upgrade along with the utg l96 http://www.trinityairsoft.com/p-1644-utg-shadow-ops-upgrade-kit.aspx and i was wondering if i would need to upgrade the trigger as well?
