If you stick with a JG gear box it will be drop in. You could just get a standard V3 shell and transfer the internals that would be cheaper than an entire gearbox.
TM are only really expensive because they are all grey imports. They are cheapish in Japan. Also other stuff is creeping up you are paying £300 and up for high end Chinese and Taiwanese gun. even guns that were a £100ish pre COVID are now pushing £200.
They have always had a mixed reputation to be fair. Never had an issue with them before other than they were closed a couple of times when i was in the area. will see what happens tomorrow. Gun was bought on a whim. receive it or refund either will be fne.
Well a bit disappointed. Order turned up today. They phoned yesterday to say a few items weren't in stock so did a few substitutions. Well substitutions present however pistol order was not and obviously they aren't open today so awaiting an email response.
No details, incorrect format, and you can get a new one in the UK for £175, and the conversion i did cost about £2 in parts ( not including the drill bit).
Did you read that before you wrote that. Extreme left influence? There hasn't been been a UK government that has even been slightly left wing since the 70s.
