Hi Whisky,
I bought mine from Defcon Airsoft and they seem decent to deal with - they gave me 5% off for ex forces, as for the rifle it seems spot on, like I said I've only got one mag so far so I haven't skirmished it yet but it has had 2-300 round's through it and accuracy at 16m is around 75mm/3" groups shot from a supported prone position with stock internals ( about the same as my Kwa mp9 SMG) and I'm wondering if some silicone oil has found its way to the bucking even though I clean and lube each sesh despite my best efforts to keep it away from anything that touches the BB - I need to buy the wurth "cleaning kit" recommend by wo1f!
As far as cycling I can report zero stoppages as should be expected.
I'm planning to run it on propane so my plan is to get all my kit - mags, fill adapter together then chrono it, adjust the mwa nozzle and hop then try and get some range time in if I can drop a fig.11 target at 50m reliably, I'm good for now till I can get some tools and a six g nub.
Cheers
Matt
