I'm somewhat interested in making a gas blowback version of one of these: https://www.wgcshop.com/products?search_From=searchBrand&item=el-aimr-aeg-platinum-version&search=special&rs=searchBrand&catid=&cat=&view_choice=b
WGC also sells the AEG front https://www.wgcshop.com/products?search_From=searchBrand&item=e-l-r-outer-barrel-assembly&search=special&rs=searchBrand&catid=&cat=&view_choice=a
Anyone know how feasible this is, starting with a WE 74U? Don't have a mill or lathe, so it would be hand tools and Dremil. Thoughts?

A few of my less serious moments (although those who know me would probably wonder if and when my more serious moments actually happen)

Probably not the case, but I've had issues with hi caps where the outer barrel rotates slightly so the bit that sticks down along the side of the hop up chamber doesn't allow it to seat properly.
But that should just be the barrel and shouldn't affect the slide. Never mind.
-
Yes. Just a tiny bit of filing on the forward horizontal partDid you file the little ramp part that interacts with the hop housing Danr?
Edit, so as not to double post: Wolf, investigate trigger over travel. I had some grip safety issues similar to what you describe when the trigger was traveling too far. Went away after I added my trigger spacer.
-
I ended up solving the Detonics/Kimber barrel issue with less than 10 seconds of filing of the barrel. Appears to work now. Going to order a whole bunch of bits to finish it off. Especially a steel hammer. As the stock Chinese pot metal hammer is looking in quite rough shape despite me only hand cycling it, and firing about 1 mag through it.
Wolf, for a lot of helpful information on the Mafioso kit, see the thread I linked to in my earlier post.

An expensive day today. Well, actually, an expensive day a while ago, but arrived today.
Mafioso Hardballer Long Slide full kit.
Clone Detonics with King Arms steel Kimber slide. To be more fully upgraded as time progresses.
Both not without problems.
Having a hammer problem with the Hardballer (http://arniesairsoft.co.uk/forums/index.php?/topic/216638-mafioso-hardballer-long-slide-problems/)
The outer barrel that comes with the Kimber slide binds when the slide is in battery. Works perfectly with the stock Detonics barrel. I'll need to file down the tab on the outer barrel that interacts with the hop up unit (can't remember the actual name of the part)

As far as I can tell, it is only for US members. Something about a username and password that I've not been able to figure out.
Seemingly no problem for other countries

Part nos.
-14 hammer
-17 sear
-20 disconnector
-24 not sure what this is called but it acts as a transfer bar tripping the sear and disconnector
On semi-auto, the sear is pivoted back, the disconnector pivoted forward. When the gun is charged and the hammer pushed back, the sear catches against the hammer. When you pull the trigger the transfer bar is pushed back which pivots the sear forward and releases the hammer. At this point the trigger and transfer bar should only move back far enough until the arm on the transfer bar just touches the disconnector.
As a shot is fired and the bolt pushing the hammer back, the trigger is still depressed which keeps the sear free. But the disconnector is also leaning more forward at this point so that the hammer catches it instead. As the trigger/transfer bar is let go, both sear and disconnector rotate backwards. Eventually the disconnector loses hold of the hammer but is kept from going forward all the way by the sear which is now in the original position from where we started.
Thanks! This will be very helpful in my further investigation.
Looks like it is as I suspected, that there is no explicit linkage between the selector and the hammer mechanism, and semi/full auto is governed by the length of trigger travel.

How does semi auto work on this thing?
The full story:
As I wait for my P90 to arrive from Uncompany (Thanks Bankz for the sale tip), I found a used, non-working one for sale. It said it wasn't shooting, but since it was going for less than the price of the mags, I figured I'd give it a go.
In that it is used, I have no idea what has and hasn't been done to it. But I do know that it was disassembled, since the previous owner painted the tan stock black. He also installed one of the trigger bar spacer things, except installed it on the wrong side of the bar. As a result of all of the tweaks and modifications, semi auto didn't function (pull the trigger and nothing happened).
The "not shooting" problem turned out to be the lever on the side of the "magwell opening" (for lack of a better term). When the previous owner had reassembled it, he hadn't properly lined up the button that gets pressed down by a magazine with the lever that pushes the valve blocker out of the way. As a result, the valve was always blocked, and could not be actuated to release gas. Problem 1 solved.
I then started to look at the semi-auto problem. With the trigger bar spacer installed the way the original owner did, the trigger bar didn't move back far enough with the limited trigger travel in the semi-auto position. I then started investigating putting the trigger bar spacer on the proper side. Based on a little bit of fiddling, I was unable to get semi-auto to work reliably. Either the spacer was too small, didn't push the trigger bar back far enough, and thus didn't fire at all; or the spacer was too big, pushed the trigger back sufficiently, but appeared to only shoot full auto no matter the selector position.
I have only had this thing in my possession for about 12 hours, most of which I spent asleep, and I'm starting with an unknown quantity with a used replica. Based on looking at the manual, and inspecting the internals (with only field stripping/removing the hammer assembly/etc.) nothing looks out of order, but I have no working example to compare to. (Just got the shipping quote from Uncompany this morning; I'd forgotten they still use the antiquated "wait for shipping quote before paying" system)
As near as I can figure out, it seems that for semi-auto to work, the trigger bar needs to move back a little bit to release the hammer, but not back far enough to engage full-auto. Unfortunately, I haven no idea which piece is actually responsible for the full-auto/semi-auto cut off.
Thanks, all.
I'm going to investigate further, but figured that some of the experts on here might be able to give me some advice/insight on how the semi/full selector function.

I recently bought one of these used, with a RA-Tech trigger set already installed.
I fiddled about with it, and everything seemed fine. However, when I used it in a game on Saturday, the semi-auto wouldn't work. I pulled the trigger, and nothing would happen (hammer did not drop).
It appears to work fine in full-auto, but semi-auto is completely unresponsive.
Any ideas on what it might be? (I'm planning on taking a more detailed look at it this evening, but since I didn't do the install of the trigger set, I haven't had any experience with taking the internals apart and putting them back together).
Thanks.
So, after the gun sat on the shelf for a while after this problem cropped up, I picked up the gun a few weeks ago. After doing a bit of racking the bolt and dry firing to see if the problem would appear, the hammer spring broke.
Just finished swapping to a new one, and as of yet, the problem hasn't recurred. I'll let you all know if the problem comes back, but for now I'm chalking it up to hammer spring degrading until it finally broke.

If you'll entertain a brief aside: where does one acquire .28g tracers? I only remember seeing up to .25g.
Thanks.

Is there a low profile rail available for the GHK 74U similar to the one in this link?
I realize that this is unrelated, but I fit an airsoft AEG gas tube rail to my WE GBB with no mortifications. May be possible on the GHK as well.
-
I was tempted to try the barrels alone and the valve alone but once I started taking apart I decided that I wasn't enthusiastic enough to deal with the complicated disassembly more
-
With the SAT valve and the SAT tightbore barrels, I chronoed at 355 with .25g BBs

I'm not sure where it was, but I developed a leak somewhere in the body of the gun before I changed the valve. I was able to stop it with a bit of silicone in the gas chamber.
-
Sadly the chrono just died. Hopefully should have access to a different one tomorrow.
No leaks thus far on propane
-
Not sure if this has been covered already, but I have installed the SAT valve in my M870, which has the Angry Gun stock kit installed.
Despite the Red Wolf description saying it wouldn't work with the AG kit, I've had no problems.
-
I've got the selector out, but the trigger box isn't coming out as smoothly as I'd hoped. As in, it isn't moving.
Edit: apparently it just needed a bit more persuasion than I was originally using. Comes out with just a bit of force
-
Has anyone removed the trigger box? The manual seems to indicate it should come out rather quickly and easily, but I'm stumped
-
Strangely enough, when I pulled it out of the case just not, it worked a lot better. I realigned the selector like you suggested (it must have been a miniscule amount, since there didn't seem to be that much play between the selector lever and internal bit). After I did that, the problem happened once more after a few test cycles, and I haven't been able to replicate it since

Has anyone seen the Hephaestus steel set in stock anywhere?
-
Thanks.
Although I am less enthusiastic about the project one I saw the price tag.

I had a 5.1 rear sight blow off due to using green (in relatively hot weather). Never had a problem with the 4.3 where the rear sight screws into the blowback unit.
In other news, does anyone know somewhere that has the infinity heroes hybrid kit in stock? Preferably the two tone version?

Glad I'm not the only one who went for the King Arms Thompson comedy load out. Was asked to be the team leader for a themed game we were holding and decided to follow the words of my old Scoutmaster: "What's worth doing is worth overdoing"
