I’ve built 3.
They aren’t the most gearbox friendly things… they take a gen9 or a V2. But getting a tpiece and gearbox that works and feeds reliable with the mags is a bit of a mission.
Mine all have JG gearboxes, SLR tpieces.
You’ll need to craft or 3d print a way to keep the tpiece stable and in place, as the barrel adaptor is too far forward to do anything and you have to work with what exists in the front of the upper.
Also have to bulk out the area between the spring retainer and receiver in front of the buffer tube, as it will pull the buffer tube upwards.
Very satisfying to get one working, as they are not an easy build to get working, feeding reliably, and straight.
And the worst news… getting a spare magazine involves buying a receiver. So if you want a few mags… you might end up building a few of them.
The third one I built was out of that predicament!
According to my Chinese friends, RokSolid here has the gen 1 version made by an unnamed manufacturer who has since disappeared off the market. Later, Ku Wu Ji made the gen 2 and then gen 3. The gen 2 had a bunch of problems which got fixed in the gen 3 but still has some problems and “special snowflake” features you have to deal with. For example the battery terminals are soldered the other way around and use a special 3D printed base. Mags also need to be slightly dremmeled for a reliable feed. I gave up and just handed mine over to our team tech to assemble as I have no where close to the amount of skills needed to put it together.

Yea ive been wracking my brain trying to get mine to work but thankfully roksolid has given some ideas to use
What problems are you facing?
The biggest problem i am having is getting something to hold the t-piece, im currently using a fighting bro gearbox but i might try a jg one instead
Sorry man, never heard of that gearbox before. Wish you all the best!
That’s odd because if it’s the shell I’m thinking of it’s listed as the FB gearbox being a straight drop in, but unsurprising.
Think I ended up printing a sleeve for the t-piece in mine but am having issues with the selector not working now, it’s not a priority build so it’s just sitting there.
Yea its the shell that states the fighting bro fits with no issues but i dont know about the selector as mines not on at the moment
Do you have a file for the sleeve you printed?
I’ll have a look tomorrow when I get home, think it was modelled for a LDT t-piece.
