Newish player would like your advice on this VSR10 build and upgrades>

Current:
JG Bar10
AA 6.03 430mm barrel
AA hop-up chamber
ML concave nub
ML bucking
rest is stock, I put these parts in a couple years ago.

I plan to get:
laylax sp150 spring
AA trigger unit and piston
ML autobot 70 bucking

Will 0.43g bb's be good? That's what I read in a post about cylinder to barrel to bb weight.
Is the ML autobot 60 or 70 better given the spring's fps. Worried 60 might be too soft.
If it makes a difference, replace ML concave nub with panthera/some other nub I've heard about?
The laylax spring goes with the AA piston I assume, do all spring guides works with this?reccomendations?
When I replace cylinder and head in future, will all the aftermarket ones be compatible with what I've got?
Anything else? Cheers.

You'll be doing fine enough, as far as plug-and-play options ML buckings will do well enough and you'd not see huge differences in practice.

Rubber softness for the most part is a myth and as long as you aren't using very stiff rubbers it wouldn't be a make-or-break thing.

Laylax spring will go with AA piston and spring guide yes, but they are both for 7mm inner diameter springs (which Laylax is). Be reminded that if you are using Rapax springs which are 9mm in inner diameter you will want to use 9mm spring guides.

I'd look at a 9mm spring guide or an adapter sleeve, a Rapax RMS spring, and a 2021 series Autobot in 70° instead of the normal one. I've used both, and vastly prefer the clear 2021 one.

I can't remember if you can use 9X13 springs in an AA piston, so you may want to wait for a second view. The Laylax spring will be fine, but APS2 springs are just better in every way.

AA pistons cannot fit 9mm springs. Grab a WASP, Springer custom works, Laylax (my favorite), TTI, or Stalker piston. They're more modern, and basically everyone agrees 13mm springs are superior.

I'd also throw a Masada arm in that chamber. It replaces the arm and nub, is super easy to work with, and will make your rifle way more consistent upon assembly/disassembly.

So to be clear:
laylax sp150 spring goes with blue AA 90* piston and any 7mm spring guide?
On evike, there is a clear autobot made for cold weather, and a normal autobot? I'm assuming the cold weather clear one is the 2021 version. I already placed the order for the normal, is it worth it to switch? I'm almost never in cold weather.

 

[Sodium]

The cold weather one (2021) is, imo, more consistent even during regular warm days. It just seems to be less sensitive to any environmental factors that may affect it.

Yes laylax springs match the aa piston. You will just get a much smoother bolt pull by moving up to 9mm spring guides and 13mm springs.
