I got my ghk m4 by accident in a bundle, it’s circa 2017-2018 and works a charm
Ive never been fortunate enough to compare it to anyone else’s, as I have never seen another one here in Scotland
The standard hop unit is next to useless
Then when you upgrade, you need to run .36’s or close to it so as your upgraded hop, won’t overhop ?
A 1J nozzle will still fire too hot over the Chrono on a nice day on green gas, so then you need to fit an NPAS system
(I’ve done this but yet to Chrono/ field it)
Mags are nigh on impossible to find, and are eye wateringly expensive if you do (like around £70 new per mag)
Used mags exchange for around the £40-£45 mark
Feedlips on the mags have a tendency to split if you look at them in the wrong direction, so then you need to get aluminium aftermarket ones, around £20 for a set for 1 magazine
Not much of a difference between Mk1 & Mk2 variants of the gun (Mk2 has a magnetic bolt lock & smoother finish to the bcg over the Mk1
Its a love hate relationship
A bit like domestic abuse I imagine
I love mine ?
