none of the metal pistols will perform as well as a TM. out of that list KWA will perform the best its a KSC/KWA design unlike the WE, KJW being TMish clones. however unless you get a sale KWA are over priced for a 20ish year old design. The chrome coating on the TM guns wears through quickly (i keep my chrome desert eagle and Detonics as display pieces) so the option is to either clear coat them or have holsters with a soft lining. As the black TM pistols are bare plastic they don't wear anywhere nearly as bad as painted guns but they are prone to getting badly scratched if gritty material gets into the holster.

in theory you are right, but in practise with out upping the pressure significantly it will use more gas and be slower to cycle. you also have a greater cool down effect as well which contributes to slower cycle rates.

but what actual range are you getting? 30m, 40m, 50m or are you just airsoft estimating? you need to actually find how far the thing shoot to be able to start any meaningful upgrades and it maybe the case it's shooting as far as it can and the money you need to dump in it to get any real increase is not worth it.

might not be relevant you need to make sure the parts you are after are not pressure baring as they will fall foul of UK law then.

try looking up VFC they're the actual manufactures

Clean the barrel go to the range with a BBs of varying find which gives the best range. If you have done that already what range are you getting Also range/ accuracy isn't really the point of an LMG they are meant to suppress to allow your team mates to get the kills.

there is not really levelling up in airsoft pretty much all guns perform roughly the same out the the box. more money will get you nicer parts more features but you are not going to see amazing leaps in performance. what do you actually want? another Armalite? personally for that money TM P90, TM AUG High Cycle, 2d hand TM G36 recoil, CYMA M14 (well under budget you could get multiple guns).

it will help a bit. However the shell loaded style revolvers just aren't very good the design does not lend its self to range or accuracy and they are more a gimmick than a useful airsoft gun. Saying that i really want one congrats on getting one they are out of stock every where.

Well just did an image search for ASG CZ75D Compact NBB and 1st of all good luck finding one. The only ones i could find in stock were the 4.5mm BB guns (definitely not airsoft). They appear to have 12mm external threads( https://www.kotte-zeller.de/asg-cz-75d-compact-style-aluminium-silencer-mit-12mm-aussengewinde-schwarz ) which is not really standard for airsoft as they either have 12mm internal threaded barrels, 14mm or 16mm externally threaded barrels.

that seems very low. what weight of BBs are you using and is the hop set? Thinking about it if the guns brand new and you are near the shop just take it back and get them to look at. better for it to be something simple than void the warranty poking about in it.

according to this it takes a stick battery in the hand guard. so 7.4v lipo stick with highest mAh you can find.

grenade launchers make a gun feel very heavy quickly. the launchers are all pretty much the same it's the shells make them actually useful. other options are ICS GLM https://www.actionhobbies.co.uk/products/ics-glm-6-round-grenade-launcher-black/ or the ELGM https://extremeairsoft.co.uk/product/acm-eglm-scr-series-grenade-launcher-module-deluxe-black/ or cool factor M79 Blooper https://www.taiwangun.com/grenade-launcher-green-gas/m79-grenade-launcher-replica-real-wood-king-arms

a warm day maybe three/four and a bit. if you are getting two mags worth you are doing pretty good tis time of year. small tank volume is effected more by cool down more so than a double stack size mag.

Are you filling the mag vertically and what is the temperature where you are? Even though it's NBB it's a small tank and will struggle in sub 10 degree temperature. If you filled it correctly and using it a room temperature something's up with it.

you could go full Antonio Banderas and convert it in to a shotgun.

Well coms have been good so far guns dispatched sharpish

Split up very few people will pay £180 for a second hand pistol even with a load of mags. I currently have a 2 pistol package sale that would cost over £400 new for £230 not a single person interested

you would need something small and programable to give you select fire again and to be honest you would be cheaper waiting for Taiwan gun to start shipping to the UK again and buy a new one for £55.00

why disregard? multi task! pretty sure Red hood was packing a pair of WE Hi Capas

other than fitting a mosfet with your current set up no idea. all i can suggest is look through this manual https://www.greekairsoft.gr/manuals/manual.asp?Manufacturer=WELL&Filename=WELL+Scorpion+R2+Manual.pdf and see what parts you still have.

should be universal. i would recomend these individual tools over the spoked ones https://www.ebay.co.uk/itm/313658049993?chn=ps&_trkparms=ispr%3D1&amdata=enc%3A1IK6TjYFtS-ubFpNE6YjMgw97&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=313658049993&targetid=1395027287896&device=c&mktype=&googleloc=1007336&poi=&campaignid=15278604175&mkgroupid=135429446288&rlsatarget=pla-1395027287896&abcId=9300698&merchantid=6995734&gclid=Cj0KCQiAk4aOBhCTARIsAFWFP9EpNUhqfqQwp5UhoPp-GNB_h82MOAh-ZBbJaHvGcs0qu1oUme4bEgkaAptuEALw_wcB

I would put money on the reason people are using an 8.4v nicad is that it came with the gun or they pulled it out of storage after 15 years.
