Arrived today.
It's heavier than a SS SolarForce L2T body.
Machining is very sharp!
Mac's Copper P60 is SNUG! Had to press it in; would not fit with a SolarForce spring.
Malkoff M61's, NB P60, and VN54 P60 modules all fit with the spring, and would work, though tools may be required to snug the head down all the way with it on.
L2T, L2M, recent production 6P, and C2 components fit great. L2P wouldn't go down all the way - even with no engine installed. Smooth, round 6P head wouldn't thread on (though it fits the other 6P, and the L2T. Kinda stumped by that one.)
As always, your mileage may vary.
I think I like the L2T and 6P the best of the ones I tried. SS on Copper is HEAVY. And I couldn't use the copper P60 with the SolarForce tail. So, until FM makes a copper head and tail, it's probably 6P components for me.
A few shots of my attempts:
Pure copper goodness:

You can see the gap with the spring installed:

SS head with 6P tail. I like this one, too.

I see I had a gap with the spring on the M61 with the L2T head. I think I had it backwards, because I'm pretty sure it worked later with the L2M - the the photo of that one is Mac's with no spring. Looks good, but won't activate. I may need to try that combo again, but it won't be anytime soon.
