I think universally they were quite high - even HK was expensive and of course these days it's through the roof. PTS MBUSs going for £70+ a set is what really gets me though. Absolutely no reason for them to be that high. Didn't know Edgar Brothers had their fingers in that pie too though.
It's cheaper to buy a G&P magazine and real steel 20rd PMag in the US, have them sent to a guy, have the internals from the G&P magazine moved into the real PMag and then ship it over here than it is to buy some of the 20rd magazines going on ZeroIn, lol.
I really likely some of the PTS Magpul MOE stuff. Damn shame that idiots worldwide were buying PTS stuff and getting annoyed when it wasn't the right spec. to the point that Magpul had to cut ties. I can see why purely from a business perspective as airsoft and military simulation must have made up an utterly minute part of their books, but it's a shame the two couldn't coexist for longer.
