Re: M4 Help.
500fps is a little warm for a semi auto, I'd say if it's ICS all you should need is a new upper gearbox, something around a 130 spring should give about 429(variable on sealing) you might find a high torque gearset might be required or motor. Steel bushings or a set of bearings will be a must, it will also need to be locked to semi auto, you would be better keeping it at your sites limit for full auto so you can multi roll, last time I took a version 2 box to 400fps for the same reasons the front of it fell off and ruined my day!

Re: M4 Help.
In my opinion youd be better off just sticking the best hop up money can buy in it, and getting a mid range scope. no ones going to be dodging any rounds travelling at 300 FPS

Re: M4 Help.
ok thanks for the reply's guys, i got a 4X30 scope on its way, i forgot to say that i got a barral upgrade, that give's me a bit of range, new motor and hopup, i was shooting at about the range of a sniper rifle, but when i got it crono'd it was shooting 375 ish, and the site says 350 max for full auto guns. so i had to remove a bit of the spring. ill put the scope on and see how it runs before i do any thing,
oh and another thing, i have a problem with my mag's/magwell i put the mag into the mag well, and it clicks, and i still have to hold under the mag for it to fire right, i mean it will fire bb's if i dont hold it but it will not all the time, do you know what this problem is?

Re: M4 Help.
sounds like either the catch in the magwell isnt clicking it in properly, and its still sort of loose. That or the mag isnt compatible with your rifle.
On the range, youre not going to lose enough range to warrant upgrades with a 25 FPS drop. youll barely notice the difference at all.
