G3 upgrades

[callofduty]

hello,

i just bought a 6.04 systema tightbore barrel
and a systema hop up rubber

will the parts fit ok into my JG G3 SG1?


i know the g3 inner barrel is 469mm but i bought a 510mm i know the length is ok because the flash hider is 40mm which compensates for it

help appreciated for my peice of mind
Cheers
Chris :D

Re: G3 upgrades

If it is anything like the Tm (which it should be a clone of),
all you do is remove the stock pins then the stock
remove the pin holding the lower reciever in.
Slide back the lower reciever, then slide out the barrel with the hop up on.

Wouldn't take me more than a minute with a screwdriver.
