I have one! Quite an early one so not sure with the revised gate or not. Assume it is as it’s pretty accurate – certainly more accurate than me!
Easy to strip - little pre-load so no compressor needed. Fiddly pop out blocks so you need a cut down allen key but apart from that – I was impressed with build quality.
I popped a V-Mach kit in which worked well. The pop up breech makes them a bit pellet fussy as mentioned (HN FTT work well). Keep power down to 10.5-11 in .22 and it’s very nice to shoot.
Get the loading sequence right or you WILL fire I with the breech still up (cock, replace underlever to closed position – insert pellet – close breech). Other good mod is Rowan set back trigger – but that’s a usual HW mod as far as I know on other HW models.
No galling issues. Yes, it is loud. No you can’t fit a silencer. Sadly no aftermarket stocks (AFAIK). Cheap.
Basically a really good fun gun.
Don’t use it for hunting but then I have a pcp for that
