Hudson Posted September 4, 2024 Author Posted September 4, 2024 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

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

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.
Hudson Posted September 5, 2024 Author Posted September 5, 2024 I'm pretty sure they were both marked mp5 in mine, the nozzle was around 21.5mm Lozart 1
Hudson Posted September 5, 2024 Author Posted September 5, 2024 Bitten the bullet and bought a new TM hop unit, so I'll be able to see if this solves the issue at least! Lozart 1
Hudson Posted September 10, 2024 Author Posted September 10, 2024 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! ? Lozart and ButcherBill 2
Hudson Posted September 10, 2024 Author Posted September 10, 2024 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.

Hudson Posted September 11, 2024 Author Posted September 11, 2024 It's still the stock one! It was purely down to the standard JG hop unit being 0.5mm off spec. Lozart 1
