300 BOT
Supposed to have a mosfet but does not metion the flawed ETU
If you look carefully the ETU pictures at airsoftzone actually show a new type receiver as fitted to SR FFR Predator's etc....
The 300 BOT is a normal CM receiver - so the pictures shown with ETU are incorrect
Also on G&G website there is no mention of a mosfet at all

note look at either the CM16 300 - polymer receiver
or
the GC16 with skull metal receiver version
None mention the mosfet nor an ETU that usually found with 3rd burst dairy lea mosfet that works/don't work depending on battery or time of the month (thank f*ck)
I have noticed a few innaccuracies on G&G site
FFR2 A2 is always listed as having a 260mm barrel but must be same as BOT's 205mm barrel coz that is what I measured it as
Retailers say it has a mosfet even a youtube review says mosfet though no mention of 3rd burst so presume basic std mosfet

So - unless you get some better clarification on the BOT
I wouldn't bother but get a CM18 instead is my personal gut feeling
As for your Raider - spray/fairy it - sod buying a new receiver - even one for about £50 tbh
it is a Raider - it will never be a TM - well yeah you could go nutz but it will still look like a Raider
Nothing wrong with that - think I'd customise it a little but sod reshelling it
No offense and it is just my opinion but just use it as it is and maybe some tweaks/service
don't go nutz though - that money should be put towards another good gun
sadly not all G&G's are highly recommended by me - but that is just my take on them
it is your money and your choice but be careful about what G&G you buy next is all I say
