Air nozzle issues

[Hudson]

Ok so there's definitely a big difference between the two then!

 

Have you managed to try the TM hop unit with a new barrel yet?

It seems like that might be usable, although it may require a different length air nozzle.

 

I shall definitely have to source one myself to test out!

 

Thank you

No problem, not had a chance I was just bored with work so I decided to take a gun apart!

 

The difference may explain why some people swear blind the nozzle for a G3 is 20mm and others say 21.4mm!

I keep the old post on my phone as a handy guide, although it's definitely outdated nowadays!

I can measure mine at the weekend when I get it apart, but I know the JG gearbox uses a tappet plated marked "MP5" so it's entirely possible they use an MP5 length nozzle which would account for the difference in hop size.

I'm pretty sure they were both marked mp5 in mine, the nozzle was around 21.5mm

Bitten the bullet and bought a new TM hop unit, so I'll be able to see if this solves the issue at least!

Ok well I got around to trying out the Marui hop unit, along with an XT barrel and everything seems to be running very well.

 

No misfeeds, drops in power or anything so far so fingers crossed, it all seems to be solved! ?

A little*too* well, in fact!

With an M95 in, and the 500mm XT barrel it was putting out 1.22J

 

Luckily this version has a quick change gearbox so with a little rummage through my bag o'springs™ it's now a satisfying 1.1J.

What size was your nozzle in the end?

[Hudson]

It's still the stock one!

 

It was purely down to the standard JG hop unit being 0.5mm off spec.
