For sale i got Tokyo Marui version of GLOCK 17. Why i wrote "VERSION" because this gun have original only a trigger. Rest of gun it's a genuine GUARDER custom parts from Tan frame to all hardened springs. I been build this pistol for 4 months, from best parts available on whole World. Looks amazing and shoot even better. Recoil spring is hand build by gunsmith in Kent, to provide real KICK!!!. Extended Mag, NINEBALL Hopup seal,Guarder 6.01mm inner barrel, that only examples what parts been used to build that grate pistol. Guarder Frame been reinforcement with steel compound to do not brake under high power. Marui mag have custom valve to provide stable output. Gun is greased with Moly grease but to achieve better rate of fire my advice is to use silicon oil. Grease is used because all parts are new and need to be lubricate properly achive a better fit at beguine of usage. Gun is after around 5000 rounds and works just PERFECT!!!!. Aluminium slide, MAGWELL and thumb support is like cherry on top. Total cost of that build was around 400 pounds so grab bargain. Grate tool for airsoft days. Bare in mind you have to be UKARA registered or paint the gun in bright colors.
