from a search, happened to notice a couple of mentions in other threads:
Nitecore P12 body using Nitecore EA11 head
Mentioned by antenne, elsewhere:
roche f-12 has a shelf for 20mm triples
they used to say the olight i3 AAA head fit the streamlight micro stream .
olight black clips from illumination supplys garage sale fits the z8 stainless zoomie (junk) and the original Mr lite blf light yeAA
Xeno diffuser TWSE v1 with the flat top fits eagletac d25a ti lights(i assume that all D25a's are the same size ) and is an amazingly nice diffuser.
I just saw a “read somewhere” note that the MtnElectronics spacers (2 different ones) for the S2 and S2+ may also fit some other lights.
Anyone know for sure?
The A6 BLF clip fits the original Convoy M1 very well. Will post a picture later.
The clip for the Roche F6 fits the Convoy S2+ really well (even better than on the F6) and it is super sturdy. However it is not a deep carry and I don’t know where these can be bought separately.
Mini-01 battery tube threads into a p60 reflector.
The 18650 Thorfire C8 body and tailcap match well with the head of the 18350 Nitecore EC11.

Other C8’s that do NOT fit the EC11:
…………… Convoy 8 …………………………… Generic “CREE” C8

Tailcaps: the tailcap of my red Convoy S2+ fits and works correctly on the battery tubes for both an Eagle Eye BLF-X6-SE and an Manker A6. (only checked one of each)
The tailcaps for both of those black lights are too tight — they start but won’t screw onto the red Convoy S2+ battery tube.
As noted above — the tolerance for variation is so large on these that a sample of one isn’t proof of any general claim about what fits what.
I’d guess somewhere there are three bins — heads, body tubes, and tailcaps — and whoever assembles the lights just keeps fishing until he finds a complete set and calls it good.
It’s the Goldilocks approach to flashlight construction. Some are too small, some are too large, some are just right.
That’s an oversimplification — threads have to be defined by several different numbers — spacing, depth, slope of the cut, maybe more. We don’t get that kind of precision.
(Or we get the seconds, if there are some that good)
Has anyone checked the threads for the retaining rings? I don’t know if those are done to any standard or not.
Could the metal switch of the red Convoy S2 take the high draw of the BLF A6 do you think?
BLF A6 pocket clip is a nice snug fit for Imalent DM21.
My Convoy red S2+ tailcap legoes with the Jaxman UV tube, and vice versa.
(that as noted above isn’t always the case, and your tailcaps may vary — but these could be twins as far as the threads and depth go.

Conformation here with the two lights I used.
S2+ tailcap fits on A6 body but not the other way around.

AAA Legos:
Maratac, Lumintop Tool, Thrunite, Prometheus Beta all swap
Maratac head on Beta Body (did not light, Maratac pill set too deep, ymmv), and Beta head on Maratac body (works!)
Thrunite head, Maratac body (works!)
Beta head, Thrunite body (works!)
Maratac head on Tool body, and vice versa (both swaps work!)
This ones a bit of a crazy one…
Takes 3 flashlights parts.
1x Ultrafire SK68, 1x Foursevens MLR2 and 1x Ultrafire C3 extension tube:
Take the switch from the Sk68, the extension tube from a C3 and stick in place of the ML2 tube.
You can now use AA and 14500 batteries with the MLR2 head!
Eagle Eyes, X6, SE body fits into Convoy S2 head and the S2 body fits on the X6 head. The S2 tailcap fits on the X6 body but X6 tailcap doesn’t work with S2 body. (similar to what hank posted earlier)
.
The old style extension tube for the Convoy C8 (from Fasttech) fits onto the Jacob body however, the tailcap for the jacob is a bit weird (requires a lot of tube to go into the tailcap) so now, the Jacob has a C8 tailcap as well.
