Help with a jg m4

[ratnest]

I've had a new jg m4 (originally a dragon). the internals are all stock. i know it needs a a whole new hop up, because one of the gears broke of, and it needs a new rubber, because the back part of the rubber where the bb goes in istorn off (honestly, i haven't been ruff at all)

I'm guessing the messed up accuracy and no velocity is caused by that.

My other problem is every few shots it double feeds. is the damaged hop up causing this, or is it something more serious?

also what hop up would be recommended to replace the stock one?

[Gunny_McSmith]

the double feeding and all that is caused by your hopup rubber blocking the bbs...so ya you should buy a new hopup unit with a rubber...(souldn't be too expensive)

PS: get a metal hopup unit...

is it hard to switch a stock hop up to a one piece metal one?

and thank for the quick reply

nah it should take you not more than 5 min to do it

Bad advice, you also need to modify the body.

Stick with a stock TM style 2 piece hopup. You won't have any feed issues with a two piece either.

would this be a good replacement?

If the gears and everything else is still intact, yes. It looks like that ones doesn't come with anything but the chamber.

having a hard time finding complete sets for an m4 that aren't a one piece, but the same site offers the hardware separately.

[Styrak]

Well what's broken? If it's only the chamber, that piece will work.

[ratnest]

one ow the gears is missing so i either need a complete hop up, or to buy the gears separately

o thats true...some m4 have a 2 piece hopup unit.... Its because i thought it was like in my hk416.... A one piece hopup unit....

Sorry

[ratnest]
