Deamos

Additionally in a brightened image I have noticed some extra Greebs on the bottom of the weapon. A large disc than the standard MP40's release disc and also a "bung" in the mag well.

I think I've sorted the sling and sling mounting method out. Using an Uncle Mike's sling similar to ones used on other Andor / SW rifles and a small addition of a mounting ring in the stock adaptor area to take a swivel sling mount. I have ended up with this and it gives the full length of the sling to enable it to go over the armour nicely. I did note in some screengrabs the guys that had the slings on in some shots then lost them when it came to the action shots. Hopefully the CNC'd versions of the Stock Adaptor and Sling Ring turn up this week.

I bow to your modelling skills as to me that pretty much looks like what we are seeing - happy to test print if with you too

I'll hold off printing your barrel and bits to see how the sizing compares to using it on the AGM Airsoft base weapon I've used. I'd say your scope mount sizing is pretty much there too and with a pair of 4x20's, one being cut down to only 5cm long added together should be about right. Only query would be around the block i mentioned before - if it is a picatinny rail block on the side of the gun it kind of doubles up the mounts and if you leave the scopes original mounting points in place as it looks like they are in some of the photo's the part in your scope mount that joins both sides together (the joining bar with cutouts) and is on both sides gets in the way. So having it only on the front side of the mount would make it work.

Just looking at the mount from this top view we can see the original flip up sight is still in place half way down the body of the weapon. and what looks to be a block coming or attached the the side of the main body. Would you think is could be a picatinny rail mount?

Just a quickie for a real world castle nut this is the one i went for but any similar sized one fits nicely over the stock hole. sourcing map M18 x 1.5mm - 1Pcs Retaining Four-Slot Slotted Round Nuts - 304 Stainless Steel Round Lock Nut for Various Rolling Bearings, Industrial Field, Silver : Amazon.co.uk: DIY & Tools

That's a much clearer shot of the barrel than I've been able to grab and shows the front "nut" before the MP40 barrel would start is still in place there, with the new barrel tube/shroud applied past it. I would say those long rails you've design also are like the ones i've added down the side of the main body above the rigger and handle area.

I've done a little colour correction on some of the gun photo's to get things brighter to see things better - one of these shows the stock is also filled in to make it solid and not open like the CYMA ones we can buy.

I'm puzzled over the barrel at the moment as while i initially thought it looked like an E11 barrel there looks to be a lack of any holes on it in one screengrab. In this one in the reference forum post you can just make out what look to be "loops" that look to be about 2" long and spaced down the length of the barrel. The connection points appear to be slightly raised from the surface as well. I've taken a stab at them and will print out what i think i "may" be talking about for a better visual representation. @Diet_Evil The barrel done does look good and if you have used the same 3d MP40 files their is a modded set which corrects the inaccurate front sight to one with the genuine more rounded shroud

Small additions to the gun to try and match the blurry screengrabs. Replacement Stock Cover: 1" Nuts bought off Amazon with a 3d printed larger screw sitting in the middle - one for either side. Repainted Body release catch: Pops out as silver on the pics so just removed and repainted. Also the grooves that are normally above this on various shots are no longer there so look to have been filled in to distance it slightly more from the base weapon. Scope Mount: Knowing this was a complete custom part it tried out my VERY basic design skills to make one to fit older, vintage 20mm tubed scope. If the sizing is about right we'll need 28-32cm long scope so this fits nicely with scopes used on other blasters like the Original Model 7 4x20 - ones on order so as soon as it arrives I'll test fit it, the one in the pic is a cheap plastic one.

As far as my info's got the only real world parts are the body being the MP40 and the Stock being the CYMA PDW. From the other information I've gleaned all extra parts were either cnc'd or printed as one offs. So that's the barrel, scope mounts and all greeblies. I've got most parts looking like the few reference shots so will post a pic tomorrow of my build so far - Posted some updates in my thread

I've had extra information that aside from the base MP40 the rest of the parts were all custom made either CNC'd or printed. So time to try my crap design skills out at the dual scope mount 🙂 Adaptor was modified to fit the AEG airsoft model and threads added to allow the stock to be screwed in / removed as needed. This will be cnc'd hopefully to bolt on to the back.

Chest / back is now done and with the pauldrons and biceps attached. Had a lovely time hitting them with a brick to get some good distressed damage to them so the weathering takes better 🙂

I think you may be right, it could do with a little less angle to it. I'll get some strapping on it tomorrow and see what it looks like then.

Based on this last picture i'd possible say it's not long enough. When looking at some of the reference pics when they have their arms holding weapons and in a "readiness" position the back is touching the bicep and wrist/hand plate. So they do look like they are covering the full forearm. I'll try and get one printed and see on my arms - did you do yours at 100%?
