blobface Posted June 2, 2017 Report Share Posted June 2, 2017 There was an HK company who sold a batch of GHK based Real Sword AKs, video showed that it cycled pretty poorly for GHK standard, but it... worked. Quote Link to post Share on other sites
renegadecow Posted June 2, 2017 Report Share Posted June 2, 2017 Might have to do with FCG pin positioning. At least with the WE it's one whole self contained unit. Quote Link to post Share on other sites
Batmause Posted June 2, 2017 Report Share Posted June 2, 2017 So, we used a DBoys/Kalash/Boyi AKs74u receiver to fit WELL AK's internals. The receiver is clearly compatible with the internals but the spring guide holder is totally different. You need to file the right cutting to let fit the spring guide. If the spring guide stuck or not move smoothly it will cause jams on the bolt carrier - can not move, stuck in a position. We didn't tested the fitting with the FCG parts yet. In the future, I can update this project if your are interested. 2 Quote Link to post Share on other sites
renegadecow Posted June 2, 2017 Report Share Posted June 2, 2017 Hmmm... just realized the stock trunnion is only held by 4 rivets vs WE's 6. This might be a critical point considering WE's recoil. Quote Link to post Share on other sites
Batmause Posted June 2, 2017 Report Share Posted June 2, 2017 Yes, but the rear trunnion was made from steel. That is why we started this conversion. Quote Link to post Share on other sites
renegadecow Posted June 2, 2017 Report Share Posted June 2, 2017 I'm thinking more on the rivets themselves. Even on the Well being steel and a copy of WE the rivets can fail. With fewer rivets that's increased load per rivet left. Quote Link to post Share on other sites

renegadecow Posted June 5, 2017 Report Share Posted June 5, 2017 Appears the franken akm/74 has a meaty recoil buffer installed. To alleviate stress on the rear trunnion/rivets? Quote Link to post Share on other sites
Dimitri MdP Posted June 5, 2017 Report Share Posted June 5, 2017 Appears the franken akm/74 has a meaty recoil buffer installed. To alleviate stress on the rear trunnion/rivets? All of the Well do have the buffer Quote Link to post Share on other sites
Batmause Posted June 6, 2017 Report Share Posted June 6, 2017 (edited) Yes, WELLs AKs have this plastic buffer. We made our own short-stroke kit which is really solid with this plastic buffer. It is a rubber buffer, if you place the original buffer behind this one, it keep the rear trunnion from this big stress. On the photo, you can see the first proto, nowadays we made them from rubber.

Batmause Posted June 21, 2017 Report Share Posted June 21, 2017 My colleague recorded a short video about how to assembly our OTs-14 conversion kit. You can see how fast to do it. Quote Link to post Share on other sites
1kenny1kenny1 Posted June 21, 2017 Report Share Posted June 21, 2017 hello all ! Thank you for this amazing Topic ! Very interesting reading also for the Groza, AWESOME JOB ! Can you make similar video of assembly for normal Groza type with the CO2 mags that comes with Well? Also please, can somebody help if we can source an Steel outer barrel for our AKS74U ? Thank you all ! Quote Link to post Share on other sites
Batmause Posted June 22, 2017 Report Share Posted June 22, 2017 Steel outer barrel: KYairsoft.com The assembly is clearly the same with the CO2 version of G74A. The gun has the same internals and externals, the only difference is that which magazine seat in the box. For CO2 version we made a short-stroke kit because the rear trunnion often break after time. The short-stroke kit will fit into the recoil spring guide with a screw thread and you need to fit with the rear, plastic buffer to make the contact surface as big as it can be.We also made a short video about how to modificate the trigger box. Sorry for the flame, I will stop if it make you angry... 1 Quote Link to post Share on other sites

Maybe you can help me with answer, I wrote to KYairsoft regarding WE outer barrel if part AK74 UN #77 (external barrel) is made from steel or aluminium. The reply was "The AK74 UN#77 are made out of aluminium not steel. Please feel free to select below link for product details: https://www.kyairsoft.com/shop/product/ak74-un-77-gbbr-29947?search=AK74+UN+%2377 Looking forward to serve you again. Feel free to ask, if there is any questions. " can you please forward me a link if you have for a steel one ? as I am searching for it like a month already Thank you also the video, yes I noticed on your youtube channel you made a video for the WELL one yesterday, great work, thank you for it. Maybe in future when I will have enough of the AKS74U variant, will make a groza from it Quote Link to post Share on other sites
Batmause Posted June 22, 2017 Report Share Posted June 22, 2017 Ouch, than I missed something. Sorry. Maybe ask a local mechanist to make the new outer barrel for you. I really looking forward the new WE AK74MN and I hope they will release the plastic stock-handguard version too - possible in OD color for a good stalker-build.

Can't you make also steel outer barrels ? You have nice kit for Groza so this would be great new extra for sure Quote Link to post Share on other sites
Dimitri MdP Posted June 22, 2017 Report Share Posted June 22, 2017 KYairsoft is wrong on that one. The short version "WE AK74UN" outer barrel is made of steel, while the full length "WE AK PMC" outer barrel is made of aluminum. 1 Quote Link to post Share on other sites

IF yes I am buying it ASAP I was searching a LOT everywhere if the WE 74UN outer barrel is steel or aluminium Quote Link to post Share on other sites
Dimitri MdP Posted June 22, 2017 Report Share Posted June 22, 2017 Got 5 WE AK74UN beside me right now (getting the team armoury ready for this weekend GBB-Only milsim ) all of them have steel outer barrels. Just checked again to be sure, and definitely it's steel.So most likely KYarisoft was wrong about that one. If you want to be 200% sure tell them to check that out for you, "people in the forums says the short barrel is steel while the long is alluminum" . They are quite quick to answer and always willing to double check, so there's nothing to loose. 2 Quote Link to post Share on other sites

Thank you Dimitri, THANK YOU SO MUCH, I wrote even on FB group, and only people owning the long one PMC AKM replied that it is aluminium, and no solid answer from the owner of the real WE AK74UN (and had it even disassembled, and know the difference between pot metal, aluminium or steel). so happy to read this, so going to order it now THANK YOU BUDDY 1 Quote Link to post Share on other sites
renegadecow Posted June 22, 2017 Report Share Posted June 22, 2017 Yup. Short is steel, long is aluminum. If you want a steel long barrel you'll need to custom graft the front half of an AEG barrel on the stock WE barrel. 1 Quote Link to post Share on other sites

Thank you buddy, ordered it and it is already on the way to me Would like to use LCT front sight that is made from steel so have to modify some adapted for it 1 Quote Link to post Share on other sites
Dimitri MdP Posted June 26, 2017 Report Share Posted June 26, 2017 (edited) Would like to use LCT front sight that is made from steel so have to modify some adapted for it IIRC the LCT front sight inner diameter is slightly wider than the outer diameter of WE's barrel So you might have to make some steel epoxy magic there.

renegadecow Posted June 26, 2017 Report Share Posted June 26, 2017 Use sheet metal as a shim. Pretty much self centering and less messy than epoxying though you could epoxy. 1 Quote Link to post Share on other sites
Dimitri MdP Posted June 26, 2017 Report Share Posted June 26, 2017 Use sheet metal as a shim. Pretty much self centering and less messy than epoxying though you could epoxy. yup, usually a single sheet of aluminum cut out off a soda can does the trick. The locking pins (or grub screw) can be the tricky part really. Quote Link to post Share on other sites
