I made my first order with Wolf Armouries recently & it's been a rather disappointing experience.
I ordered a Tokyo Marui KSG from Wolf Armouries over the Easter weekend. They were doing an offer of 5% off guns/10% off accessories so the price was decent & I also bought an pack of extra shells with it. Shipment/delivery was fast (it was sent the following Tuesday and delivered the next day, Wednesday 15th) and it was well packed - all good so far.
Unfortunately it looks like Marui's QC dropped the ball on this KSG as the one I received was defective - the pump locked up in the rear position before I was even able to fire it once

In addition to that the gas tank seems to fit quite tightly and I had to push it out from the chamber side to remove it (it's possible that may just be because it's new and needs to be broken in a bit, but none of the reviews I read mentioned this and videos showed the tank popping out easily by itself when the release lever was pressed).
Anyway I emailed Wolf Armouries about it and waited. A couple of days later I hadn't received any reply so that Friday I tried the contact form on their website in case my first email didn't go through or otherwise was missed (it was sent as a reply to the order confirmation).
That message did get through to them and they sent me a reply a few hours later wanting my phone number so their engineer could ask some questions before they arrange a collection, however I didn't notice & reply to it until late on Monday because gmail had marked it as spam. I asked to deal with it via email as that would be a lot easier for me, and in anticipation of their questions described exactly what had happened with the KSG in as much detail as I could.
I still hadn't received a reply to this by Friday - and I'd been sure to regularly check my spam this time so I wouldn't miss any more of their emails - so I tried the contact form again and included the reply with it.
As of today I still haven't heard back from Wolf Armouries. I understand that things will be slower than usual due to the lockdown, but it's now been two weeks since the KSG was delivered and I first contacted them, and almost a week after I last tried contacting them, and I still seem to be no closer to getting this resolved.
