CA G3 SG1 Reassembly problems. HELP!

[Connorburton96]

Hi I'm quite new to the sport. ( 3-4 months ) I got a classic army g3 sg1 2 ish months ago and I took it apart the other night and when I put it back together it started to make a clunk when you shoot it? The noise is quite loud an the gun vibrates a little in-between the selector switch and start of the hand guard?

Iv got no idea what to do?

Any suggestions ?

Thanks :huh:

Is it actually firing properly? Did you open up the gearbox previously?

 

[Connorburton96]

Nope it's stopped firing altogether

Thanks

And no I didn't touch the gear box? Other than removing the lower reciver.

Well if you've checked everything over, I think the best bet for you would be to let someone have a look at it down at your local site.
