By the time everyone is kitted out as whatever their version of a super-cereal secret-squirrel-weekend warrior is you can barely distinguish people by the camo they're wearing and the gat they're wielding.
Whatever someone otherwise presents as the only thing that should matter is if they play...
Am i the only one who thinks that only shooting a gat a few times before getting rid of it implies it's shit and thats why you want to get rid of it?
Kinda like how a secondhand car that's 3 years old with 5 owners, whats so bad about it that nobody wants to keep it longer than a year?
a test is to assemble the upper+lower without the inner barrel/hop assembly see if it's still tight, will tell you if the hob is being jammed in there or if the gun is just a bit tight.
Pushing the hop unit up tight to the gearbox, which to a certain extend is exactly what you want. Indeed using o rings round the outer barrel rather than a spring the purpose is to acheive exactly that and even to the point where the pin needs a little tapping to get it in/out.
Does double duty...
the nozzle length is just a case of getting a longer nozzle, there will be a correct size for your particular gat.
you don't need to seal the gearbox to the hop unit, the key seals are:
piston o-ring to piston rear face
piston o ring to cylinder
cylinder to cylinder head
cylinder head to...
if the nozzle is too long the issue is that when it retracts it isn't far enough back for enough time for a bb to be brought up to the firing line.
you holding it back against the pin? does it feel like when you're pushing the pin into place that the reciever is moving even further back?
Does sound like nozzle length, assuming it's aftermarket then you want to check it against oem.
Certain hop rubbers (particularly maple leaf) in *some* guns the feedlips can protrude back into the hop chamber and acheive a similar effect. My go to for such cases was the pdi w-hop with standard...
I suspect if e locking isn't good enough then every solenoid based hpa dmr is naughty as they can be changed to fa via fcu settings.
I remember one of my battle buddies contemplating doing the inverse to run my hpa'd mg42 in cqb, purely for the hilarity of running the literal worst cqb gun...
shell ejection puts this more into the "pretty prop for re-enactors" rather than a skirmishable gun.
shame as if i were to get back into the hobby i can see my comeback going for a lightweight mosin-and-a-prayer style.
The mag bodies are nice, at least the steelies are.
Its just the springs and followers are crap and its not that hard to swap the guts with cyma springs/followers to get pretty and reliable mags.
