Finally got around to pulling that MP5 apart.
The culprit…
But this just showed up.
EDIT: turns out the LDT cylinder head doesn’t fit the LDT gearbox… who would of thunk.
But this just showed up.
Seen plenty of those little “two part” springs before!
Softer cheaper springs last longer than the more fragile stainless steel or high tensile ones in standard configuration……… but SS/HT Springs can be reshaped from new to allow for more lineal flexibility without developing stress fractures at the critical end coils to make them virtually indestructible when shaped right

I ended up just replacing the spring with one in my parts box, don’t know what sort it was didn’t look like SS.
When/if something else fails I’ll look more into better springs etc but for now it’s running and shooting.
Oddly it’s hating hardened gels but runs great on the condom pack blue gels (got sent like 20 of those little packets with the blaster)
And with that little internal hopup they come with it’s shooting pretty accurate too.

Believe it or not, I did probably 90% of my new OOTB testing and Chrono results using those Blue supplied gels, as I had thousands of them piling up in a box and wanted to get rid of them somehow……… but they were actually surprisingly good and gave no issues no matter what I put them into!
Many of my old FPS Tests would quite regularly outperform other peoples same model new stock blasters by 20+ FPS, and I could only put it down to the cheap Blue Gels, because when I ran higher quality/harder gels through the same blaster, the FPS would actually drop down to whatever results most other people were experiencing who were testing using better quality gels

Because the nylon gearbox is made by warinterest. LDT latest parts such as the tappetless nozzle and gearboxes are not produced by warinterest anymore…

thats so coooool
I want one immediately
MP5 not shooting too bad, air seal on stock parts was pretty AVG but didn’t have spares to fix it up, will eventually the not should shoot pretty good
And just need to do the stock, main barrel and sand down some clearances and it should be good to go

Yeah, I’ve always said about the LDT MP5s, it’s a damn shame such a good shell has to be fitted with such a shitter of a W.I. gearbox.
Good that you’re getting it sorted though… nice!

I’d just invest in a whole nother gearbox. The more you pull those WI boxes apart, they start falling apart themselves. The gb shells are made of plastic dinner plates recycled.
Finally got around to starting the MK47 build ive been wanting to do for a while, waiting on a few parts and doing custom wiring for the P* loom. just running a jack in this one.

Very keen on that handguard for one of my mp5’s, does a simple stl search yield results for that?
Umm yeah it was on thingy, hold up.
edit:
CYMA MP5 Magpul inspired handguard by DannyTheNoob - Thingiverse
you can print it with thin fuzzy settings to get that texture effect. only issues with the LDT is the front pin is longer, so it sticks out a bit, and the model goes over the receiver rather than using those two tabs on the inside, but it holds it sturdy enough.

Cheers
not an issue with the pin, i’ll modify the STL to suit 
Yeah all you gotta do is thicken around the hole by about 5mm I think and it should fit right.

@ZeGerman love me a mutant. And that looks awesome. (except for the hose but thats the brakes for HPA! more a fault with me than HPA though)
I gotta let this out though. As I was genuinely disappointed at Azraels for this… Their receiver is closer to an SR47, not a CMMG MK47… nitpicking I know, but it seems nobody has ever noticed or said anything.
SR47 - Was a knight’s armament SR15 that was parts changed to suit captured insurgent AK mags, the program was a failure due to captured ammo in this scenario is almost always trash, and 7.62x39 doesn’t do well on parts and receivers designed for 5.56. I think only 6 were made, with only one left in the KAC museum.
MK47
CMMG basically doing the same thing, but with an AR10 base, and it was made from ground up to suit 7.62x39. The main difference externally is the magwell, which is also my main nitpick int the naming convention used.
I know I am being picky on the details, both are an M4 that takes AK mags, both are a travesty of east and west, both are very cool imo also.

Thanks mate.
Yeah i’m aware of the innacuracies but as far as options for making a working blaster its either the azraels or the other one (which i have the reciever for) and then its the quest for the holy grail to find the mags 
If we had the CMMG version here in aus i’d def have build from that instead.
That being said the Azraels reciever is really nice looking… i am interested to see how it holds up to milsims and me crawling around / falling over

Battery fits in there ok obviously.
Can always paint it, the grey would look like bare metal with any wear marks.

Made an adaptor to use a folding stock instead of the collapsible one, need to remodel the attachment so it actually locks on the rail instead of just friction fit cause that’s logical for a stock.
And a different one
And the collapsible with the shotgun under barrel
Haven’t been motivated to dig out the power tools to work on the other projects lately but eventually.
