Guarder SP120 Full Tune-Up Kit for Mod5 / MP5 Series Airsoft AEG

1 Customer Review

"this tune up kit is worth the money. there are other things though that you might have to get such as a a stronger gearbox. the only bad thing about this tune up kit are the bushings amd the air nozzle it came with. the bushing couldn't be properly installed. they didn't fit cause they were a little on the small size. this might be because i took them out of my TM gearbox. The air nozzle was just plain crap. it kept chipping and when it broke, my fps became like 150. When everything was working, the gearbox was putting out at 415 fps. good buy. just replace the air nozzle for sure
