r/40_mm

Im not sure if I still have a 37mm launcher. Or at least one suitable for these.

Back again! Completely reworked the latching mechanism from my previous design. Its no longer click adjustable, but uses a hardened steel pin on a plunger to slot into the side arms. It's now super solid and honesty probably overbuilt.

Im still working on a few things such as figuring out the angle and range relationship of 3d printed 40mm rounds. Next version will only have slots for 50yards out to 250 yards with 50 yard increments which should reduce the overall height of the mount. After that is finding somewhere to finish the laser cut parts and get them color black so its not such an eye sore. I might look into having the base and rail machined, but that's not a super high priority.

And I made my childhood dream come true! I have always been enamored with the B&T GL-06 ever since I saw the airsoft version. I was never able to get one since my airsoft budget was extremely limited back then but I’ll settle for the real deal now. Hope you all enjoy!

So I’ve been seeing these “nipple rounds” with something called a point detonating device in them. I believe the technician designation is M183a1. So my question is, what are they and what is the legality around them? Do I need an FEL to own, buy, or shoot them, and do they have special requirements like when loading blanks into 40mm cases? Thank you everyone as always.

Has anyone ever used a canon fuse for delays? Does it ignite reliably. My idea is to use heat shrink to avoid premature ignition. And coat the ignition end with a slurry of gunpowder dissolved in Acetone. Once the Acetone is evaporated you get this super easy to ignite end piece.

I was looking at these

Do these actually fit inside a M203 and has anyone used these? I know this dude takes forever to ship I just don't want to buy them and I can't use them in a launcher.

I got these four. On top of the other 3 in process. Yes. I am a 40mm hoe. 🤣🤣. I had to buy at the prices though. I am sure they will look at the transfers and think what the H lol. Thank goodness everyone it seems has like 50 form 1s pending 🤣🤣🤣

Finally got a CTS bean bag projectile. They’re even simpler to make than I thought, no sewing or anything. The balloon is full of very fine sand.

About a 10” length of fabric sleeve, tied in the middle with a string, balloon goes in one end, roll the other side over and tie another string around the sleeves behind the balloon.

Link to a roughly similar Kevlar sleeve material in comments.
