APS XTP ACP bolts fronts have been added

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 support
nozzle spring guide (is all ready a beta thing)

For beta user 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

1-3-2024

new disconnect bar have been added that will work with the new fire pin assembles 
M1D and M1E these can be found here for now.

--------------------------------------

16-12-2023

bolt fronts with spring guide have been added
 

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

--

13-12-2023
the H lower to H upper disconnect have been updated I made a error that is now fixed


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 BL 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
and a UNW hopup cut out have been applied.

 

In case for old BL uses: it’s not necessary to reprint the upper, but you do need to manually make the space for the disconnect lager. This not a hard thing to do. It’s explained in the FGC-6 H how to build manual what needs to be done (will be later added in the BL PDF as well

https://drive.google.com/drive/folders/1XBZvTm_s3VLk_iqTnINIyMt30BXmXn8h  (page 30)

the disconnects
are updated to work with the new Lock pin fire assembly that are at the moment a separate beta. 

https://www.printables.com/model/677286-fgc-6-h-bl-sf-locked-fire-pin-beta-set-set-gbb-air

In case for old BL uses: Keep in mind that the disconnect part need to be chanced in case you want to try out the new Lock pin fire assembly. And since it’s harder to update the old BL lowers did I made a BL lower to H upper disconnect option

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

https://www.printables.com/model/676226-fgc-6sf-parts-set-for-fgc-6h-and-fgc-6bl-parts-set

Bolt fronts
they have been updated to work with the new UNW hop up unit (beta)

12-10-2023
new V2 hammer added. improvements are tested on the SF and should also be better on H and BL models. but I leave the old model in te set just in case you find it a better model

-

13-10-2023

new v3 hammer added this one is definitely a replacement for the gen 1 hammer. but I will explain the difference in a video so you can see what the V1 , v2 v3 is all about

-
___________________________________________________

if correctly assembled then the 3d printed wheel should work okay, but it can’t compete to a actual role bearing of course so since this is a easy update to make is it worth to replace the 3d printed wheel for this part and see it as new standard.

but I have to be fair I have done not extensive testing on this at this point.

thanks to N8 for playing around with this concept, and Gibbs  for testing this out as well.

-

compatibility note
is can be installed on the stock hammer but I do think it’s better to reprint the new model for this. but feel free to simply try the replace the 3d printed wheel for the roller bearing.

so long your roller bearing is the right size and bolt. then it should be a drop in replacement

the FGC-6BL is here making this the first hammer fired semi auto GBB FGC-9 airsoft replica to be released. there will be later also a FGC-6H this will be the 1 on 1 replica in function and handling from the FGC-9. but the BL is very close to this as well the only difference is that the bolt will be partly open when the last round have been fired.

I can’t make any guarantees of course since the FGC-6H is not finished but the idea is that you only need to reprint the BOLT, HAMMER, and some small disconnect parts to switch between the FGC-6BL and the FGC-6H

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-6BL MKI or MKI collections

FGC-6BL MKI and Hybrid
https://www.printables.com/social/180009-untangleworks/collections/492098 

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

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
