Is this your first gun? If it is, Learn to play without any upgrades.
Anywho will give you the usual upgrade. PDI 150% Spring, Metal Bushings, New Spring Guide. If you like, add a 6.04mm Tightbore Inner barrel. (My G3SG1 was damn fuckin accuarte with this.)
As for a metal clink/bolt action type sound while cocking the gun, NO, that option is non-existent. As far as I have seen & searched. It is only available for the TM Sig 552's.
