I've just bought something in their sale so I'll let you know how it goes ?. I used PayPal in case there are issues. It looks like it's a shop tied to an airsoft site I think.
@DanielDefenceWell it arrived today and I'm happy with it. It works and the mag is gas tight. They delivered using parcel2go which then used Yodel. The true test of any retailer is to see how they behave when there's a problem, but no issues here with the RIF. A few bargains in their sales section (at least there were last week)
