G3 replicas run a Version 2 gearbox but not an M4 nozzle, which catches out plenty of people servicing one for the first time.
The mistake is understandable and expensive: fit an M4 nozzle to a G3 and the gun will misfeed from the first magazine.

Good to know before you buy
The G3 catches out first-time servicers more than most guns, purely because of the Version 2 assumption.
Frequently asked questions
It has a Version 2 gearbox, so why not an M4 nozzle?
Gearbox version and nozzle length are independent. The G3 uses its own length despite sharing the shell type.
Does it cover the MC51 and shortened G3 variants?
Those usually share the G3 nozzle length, but shortened builds vary. Measure before ordering.
What else should I check while I am in there?
The tappet plate and the cylinder head pad. Both wear alongside the nozzle and both cause the same feeding symptoms.
