ok then you are right in getting a mosfet to run a Lipo battery but you could the gearbox to cycle without it !
but enyway get your mosfet but be aware that some are merely burst fire gimmics so reserch on youtube what otheres are using
great store been many times as it is my local . plus if you can get to the store they have a little discount section, i got a g&p vers 2 gearbox with mosfet installed for 60 quid and it works a dream
i think as long as the owner of a RIF is not a d**k then its ok ,but on the othere hand we need to show we eat rules and regulations for breakfast and show that we are doing the hole airsoft thing by the book instead of being looked down on because we love guns
the WE scar-l is a good gun but it will need an n-pas kit to tune it down as its fires realy hot at about 430 to 450 fps also the gas mags are dreadful in every way as you may forget to put gas in them after use and next time you operate the gun the mag leaks like hell and loading bb's isn't...
