small update on the M1D fire pin and left frame to act as a mag stop. and prevent gas from escaping when the mag is over inserted

---

16-06-2014
new bolt fronts added it's highly recommended to update to this bolt front. So the nozzle cant fly out the front of the bolt in case of some tolerance issues. This update does not apply to AAP01 nozzles.
But this would bend the nozzle spring and gives ware on the nozzle that is unwanted.

A BIG 2024 project update is a view weeks away!!!
so my recommendation is to put your build on hold.

Barrel / UNW hop up unit will be updated
Bolts will be updated
bolt front caps

internal pars will be updated

and the manual

why? Better FPS/joule out putt
a more easy and relabel build
better nozzle
nozzle spring guide (is all ready a beta thing)

For beta keep in mind that I’m working and testing parts that are newer then the beta parts.

When this update is done and it’s confirmed that it is good update. Then there will be 2 alternate models added over time. The stingray, and partisan 6 edition of this project. In a H and BL version

(cults3d note, at the moment I’m working on a lot of improvements so keep a eye on the discord and printbels for some bata parts. After that is closed the cults3d version will be fully updated)

to day I discovered that I made a error with the nozzle spring placement. so even do the spring guide helps. do I recommend to reprint the bolt front! to prevent nozzle spring damage

also I have added for the WE / AW G 18 nozzle

the TM model is still a work in progress

bolt fronts with spring guide have been added
https://youtu.be/Z7I6xw9x5wM

and the extended charging handle bushings for MKII s that was made for the FA models in case you prefer that model.

11-12-2023 Lockpin / project streamlining update

the lowers
have been switched for the H model lower.
These can be used for FA, BL and H models.

In case for old H uses: it’s not necessary to reprint the lower. But for new builds it’s recommended to use the new parts of course

the uppers
the uppers have been updated to the H model upper that will work for BL and SF models as well
and a UNW hopup cut out have been applied.

In case for old H uses: it’s very easy to mod it for the new hopup system, so no need to reprint things.

Bolts
the bolts are now lock pin ready, besides that there are no big updates made on them.
Also Keep in mind that a SF bolt can also work as a semi auto bolt for a H build in case you want to have more flexibility. In regards to semi auto and full auto fire options later on

Bolt fronts

-

the moment is finally here. the FGC-6 now called FGC-6H is finally here after a lot of chances to replicate the FGC-9 as close as possible as a airsoft model is it finally here.

in case you want to read more about the FGC-6H and his side projects before you start building one. then look at the PDF: FGC6 project explained

this kit comes with a lot of options! so read the PDF’s well before you start so you know what to select to print and buy.

this project have been tested with green gas, red gas and HPA and it got a working range with the current springs of 80/90 up to 140 Psi on HPA.

look for shrouds and stock in the FGC-6H MKI or MKI collections

https://www.printables.com/@UntangleWORKS/collections/451551

FGC-6H MKII / MKIISD link:
https://www.printables.com/@UntangleWORKS/collections/451552

the advanced parts will be released in a separate package. note: only use them as fine tuning and experimental parts! your FGC-6H should work with the parts provided in this starter kit.

note to printable s: you have to scroll down and also all other files! to get you hands on the PDF’s

print settings:
0.2 layer hight should be fine.
you can use the 8 layer walls and a 40% infill.
but personally I moved a bit over to solid prints just to give it more strength in case things go wrong on the field…

for the lower I would use a brim on both the outside and inside the part just to prevent it from warping
