Hmm 2nd thoughts about purchasing now… im not a fan of bendy T-peices (which i believe the JINMING has?
To be fair i dont care about any of the internals (except T-peice) as im going to HPA it.
Would you know if the barrel/tpeice block (that bit of metal they all have) of a LDT would fit into the JINMING upper? that might be a way for me to solve the t-peice issue?
Not sure.
I haven’t pulled my JM fully apart yet…
Seriously thinking about pulling the trigger on that JM…
If I do, I’ll tear it down and do a deep dive thread on it, you know I don’t give two shits about warranties… 
Enquiring minds seem to wanna know.

honestly it’s not just about the warranty or lack of knowledge, time is also of the essence, a valuable commodity I often lack, also motivation and appropriate tools

Maybe hold off, till we get a few reports about the faulty ones…
Also, did you ever post the gearbox photos, of the LDT pulled apart.?
There are faulty ones?
Read the JM post…
2 have failed so far…
Wombats failed, first game out…
Yep, just did… 
Hmmmm… interesting development. Yours is still okay though, yeah?
Yeah…but minimal use…
Do you have the photos of the LDT box pulled apart…?
Errr… I only took one photo that day… of the LDT gearbox.
Well… I never said I was much of a cinematographer. 
I’ll make a better effort to take more pics when you do the next teardown.

Update on the LDT mp5k Performance…
Went up to @Friendly_Fire s place, and did a bit of an experiment, in impromptu barrel lengthening…
As you might remember, last time we upgraded with quality components for the nozzle, cylinder head, and piston head, and a M100 spring.
The air seal was fantastic, but negligable performance gains…
So, today we did “Claytons barrel lengthening”
(different barrel lengths added, and retained by a very tight piece of tubing).
SMALL extension…
( just a bit longer than JM version)
LONG extension…

When all is said and done, the approx barrel lengths were…
Standard … 11cm
SMALL ext…16cm
LONG ext…33cm
Using ultra elites, the fps range was…
Standard 190-200 fps
SMALL 230-240 fps
LONG 290-310 fps.
This proves, the seal is fine, and M100 performance is hampered by the small (tiny) barrel.
Standard the LDT barrel is shorter than the JM barrel by 5-6 cm, so the JM will get marginally better performance stock.
I was seeing 200-220 out of the JM standard.
The shorter LDT barrel, is basically a pistol barrel.
I do like the look of the MP5-k without the tri-lug, so “it is what it is”…
if you wanted to CQB, you could put on the SMALL temp barrel for the day, its VERY tight, and would give you a reasonable boost.
I’d be happy to leave the barrel longer on my JM, and see what performance gains can be had there…
dang it … i paid $172 (x 2)
the grip-battery life will be interesting for extreme CQB gaming too
I think this proves you need to change the cylinder
what actual difference, do you think the ported cylinder would acheive, at each barrel length.?
Better VE, more accuracy. Less stress on the drivetrain.
And with good VE comes that satisfying quiet thump when it cycles instead of the crack of an overvolumed barrel.
Interestingly for comparison, you’ve got some porting in that LDT… around 80%.
The Jin Ming is running a 100% cylinder.
