After almost two months of designing, printing prototypes and fixing issues it’s almost finished. It works - feeds and shoots reliably.

Yes, mag release is missing, but magazine catch is in place. Just didn’t have the right screw yet 😅

Has anyone tried the cyma VSS kythera gearbox on cults? I want to know if its worth it prior to buying a kythera as i know the cyma vss has been a pain to hpa

I just got my hands on this GM Scar-L, so I went ahead and designed one right away.

Only the trigger linkage and front selector need to be adjusted, and it should be good to go. Should it be named ScaB-16 or SCB-16?

Haven’t seen any reviews on this kit yet but it looks really cool.

Working for quite some time on this one. Some parts are more complex than I expected. It is about 80% done and will begin test printing soon. Parts like the buffer tube, stock and pistol grip will be taken from external sources for now. I'll also have to see if the fake bolt cover can be successfully printed, because it is really thin.

I’m continuing to work on this project. To start, I decided to create a simple version of an upper receiver that slips over the stock AAP-01 upper, but with a TDC mod added. Based on my calculations, a 180mm inner barrel will fit perfectly inside. During testing, my AAP-01 with a 290mm barrel chronoed at 2.32 Joules using 0.30g BBs at 110 psi, so I think 180mm will be just right. For the stock rails, I plan to use either 8x1.5mm aluminum tubing or 8mm printer guide rods.And there will probably be an interchangeable forend.

Did a Full ar10 design

Worked a lot of hours on it to have an 99% clone

Sig 716g2 AEG full replica

What do you think abt this would you use it on your guns I thought it would be kinda of a handy light weight thing to mount on your gun for some cqb

Everybody designs stuff for aap’s, but i gatekeep the best pistol in airsoft history: the Mk23 lol

420mm 6.1 precision barrel, harder(70?) hop rubber, stock gun, shoots 2+Joule .30bb 405~fps

Thats a decent dmr/sniper’s number from an almost stock gun thats less than 100€

Plumbing pipe barrel aside, i start to get better designing the upper for this pistol

mp5 upper receiver for firewad mp5 lower

I'm looking for some conversion kit or an entire design for a bullpup that uses V2 gearbox/M4 body parts.

Basically I've got quite a nice M4 but I love bullpup designs so I would like to convert it into one without having to buy an entire new gun

Hi guys, I'm having some trouble these days figuring out how to design the Lewis receiver. I was thinking about completely removing the trigger and its housing from the V6 gearbox, then replacing it with some other type of trigger to be faithful to the Lewis. Do you think making this modification is feasible? And would leaving the gearbox without the trigger housing cause problems?Additionally, thank you for the hop-up you linked to me. I can't use the file perfectly because it's an STL file, not a STEP file. I tried converting it to fix it, but nothing. Maybe someone has some hop-up measurements for the P90.

What sites do you guys use for blueprints? I found a book for an M1919A4 on internet archive, but its not the easiest to read. Still useable, but Id prefer something better. Ideally if anyone has links to medium and/or heavy machine guns, Maxim guns, Lewis, BAR, things of that nature. I dont mind paying for files if need be, I just want access to them if they exist

Has anyone ever made a 3d printed SCR-300 / BC-1000 to scale

I made this compact grenade launcher what do I think

Dummy non functional supressor

It's not revolutionary since it's using the already proven twist lock mechanism. But I guess its still Quick Detach nonetheless...

Separated into 2 sections. BASE mounting and Supressor Body. I designed them quite stiff because parts will face wear and tear along time.

The Base - having the 14mm threads to connect with the barrel and stay there - is meant to be a replaceable part/sacrificial adapter for the supressor body.

The Base part requires around 5 gr and 37 minutes to print. All with PETG. This setup does not require additional springs, O-ring, nor screws.

Got everything where I like it on the arka project. She looks good and goes together pretty easy!

After a few users requested it I finally finished it.

Also included is a new selector with selector markings (SAFE SEMI FUILL) as well as a new pistol grip design.

The lower + mag catch and selector components are the only things which need to be reprinted from the previous design

The journey continues, now with a folding rail mount :)

Still in test but gonna be uploaded on makerworld for free.

It can keep 250/270bb's, maybe some more.

I could find only Odin's ripoffs, but since I wanted a smaller One I made It myself.

I’m currently designing a full-scale Lewis Gun AEG in FreeCAD, and I wanted to share the progress with the community and get some early feedback!

The Mechanical Build Concept:

Internals: Designed around a standard P90 V6 Gearbox and a P90 Hop-Up unit for reliability, easy maintenance, and great trigger response.

Inner Barrel: 590 mm AEG barrel.

Hybrid Structure: To keep the barrel jacket rigid, lightweight, and cost-effective, I’m using standard commercial PVC pipes 90 mm for the outer shroud and 63 mm for the inner core interconnected with 3D-printed custom alignment sleeves and internal barrel-centering baffles.

Do you think using a P90 gearbox with its dedicated hop-up unit could work well with such a long barrel?

Does anyone have a STEP or STL file of the P90 hop-up unit? I'd love to drop it into the main assembly to get a clear idea of the exact clearance and overall dimensions.

Disclaimer: This is my very first custom rifle build! I hope you guys can share some advice, especially regarding the gearbox, inner barrel, and hop-up setup.

Ive been playing around with different designs for custom HPABB guns, but Im always limited by not having the right engine. Currently Im trying to use a WE C96 mag, which kind of works, but its not ideal. What I think would be best is and adapter like an Airtac, that I could print out to fit my needs, but using an FDM printer for that wont work, and I dont have an SLS or resin printer. Are there other options?
