How many shot per/sec do you consider as fast?

im nto sure but if i try and do a double tap the 2nd shot wont actualy fire it will just kinda buzz at me

I bought some TM 100 round MP5 mags a while back, and I couldn't load more than 50 BBs into them at first. I had to put a significant amount of oil in the mags and reload them several times to finally loosen everything up so that I could fully load them. Now they work like a charm.

ya brian was tel me its the spring prolly not wanting to go around one of the bends in the track. im gonna take one of them thats all broken for some reason and crack her open to have a look

This in my opinion as to do with the switch. Or motor could be too week. Is your gun stock?

yup, havent done anything to it yet
