[Curtis Tactics]

yes your battery will be hard to fit. i have a 9.6 3500mah battery and it barely fits. i took out the two prongs in the stock and shaved parts of the battery. also in order for it to fit i now have to take the whole butt off to take it out. it helps to also make a butt extender out of abs. ill post pictures later.
if your purchasing from buyairsoft.ca they have metal bearings (bushings??)
you might want to get a spring guide for that 120
