It uses a carrier but it is not plastic, it is all metal construction and has a built in 2A USB C charger / battery bank.
Im in for a silver.
Yes, I DEFINITELY prefer to have charging on the battery carrier, like the K1, it makes for more reliable waterproofing, a better aesthetic, no worn out "boot" over time, and the option to buy back up carriers for easy swap & go.
Yes please, leave the hints of machining and not bead blast, just clear ano aluminum. A new light of mine just came in (ano aluminum) and has machining marks and it really adds a nice aesthetic. my first one didn't have this and i really prefer it.
That battery tube machining / design is awesome!
I would like silver if available!
He is checking to see how long it would take to make more silver since that is what everyone so far has wanted lol.
:+1: :partying_face:
In for a RAW.
Will the high drain cells be best for this light? I have 40T’s & 30T’s
Looks good! Interested for silver or black.
I didn’t see mention of it, but is there a way to ensure the cell carriers can accept flat top batteries? This way standard high drain / high amp 21700’s (30t, 40t, etc). can be used without the need for solder blobs and, even worse, tac welded button tops. Thanks TA
So two or three thoughts here …
3p 21700 is a lot of capacity. 2A is okay, but QC or 3A charging would be ideal. C-C should be a must.
I think that with a light this size, carrier based charging is a choice. For use as a power bank, it is nearly a necessity. My recommendation here is for the development of a plastic enclosure for it. Something from PC ideally but whatever is cost effective and can provide enough protection and containment of the cells for safe use and luggage in a backpack for example.
Lastly is my thoughts on how to make these upgraded parts available. I’d suggest shipping the lights as they are now basically, and offering carrier upgrade kits for early buyers at a super sweet price 
Will they include batteries?
In for one clear/silver, thanks.
Interested…
I wonder how long can it last in Turbo mode typically before starting to stepdown (I understand it’s possible to turn off stepdown in Narsil — will that be ‘still safe’ for the flashlight? (this may make the flashlight too hot to hold though… but flashaholics probably understand the trade-off…)
When will they go into regular production and not just group buy?
How does the 3 x 21700 config compare to the 4 x 18650 config in the MF02S?
This light looks pretty impressive.
I think the 3x 21700 setup is really smart, though I don't do multi-lithium-ion flashlights. 
I’m in for 1 silver thanks Texas_Ace.
If I’m in it will be for a black one. But I’m hot decided yet, it competes my FT03-SBT90.2. That one is between 400 and 500 kcd throw so just half of the Wildtrail, but it is way smaller/lightweight too. Decisions….
Yeah, high drain cells will work best, although it will work fine with any 21700 to be honest, just lower output naturally.
