No parting out. About %80 original tm g17/22 Had guarder lightweight bbu We nozzle (all my mags where we so.....) Stainless steel recoil rod Tuned hammer so it's smooth Timberwolf outer barrel Upgraded 150% hammer spring If you don't know tm makes these with plastic slides but these ones have the metal reinforced front to stop the cracking issue. Built it as an ultra light but don't use it as often as I would like so just selling it now. $200 obo
