How do I test this without it being in my hand?

If anyone's wondering, you have to smack the back of it for it to go boom

Potential new project (random AliExpress junk)

Found this listing for an interesting item, has little in terms of what it exactly is. Has some key terms like "bird repellent" and shows up when you search "fireworks launcher"

It's pricey but kinda looks cool, I hypothesize with some modifications it could be a cool break action black powder cannon/ muzzleloader. It's on my purchase list, I'll let y'all know if I end up picking it up anytime soon.

The video shows it with a slit in the side but product images show otherwise. 🤔

It says it's $623 but its actually $68 bucks plus shipping.

Just thought y'all might be interested in seeing it, and what y'all thought.

I just found this on AliExpress: $623.14 | Furniture Art Decor Two Kick Stand! Stainless Steel Handicraft Auxiliary Function Bird Repellent Gun https://a.aliexpress.com/_mM507ht

Floating gas piston on bolt carrier?

Is it necessary to have the long stroke gas piston unit fixed to the bolt carrier instead of just milling a slot for it?

Insane twist rate, or rather no rifling at all? (.22 derringer plinker)

As the title says, twist rate accidentally came out at 1:6 twist rate instead of 1:16😂 would you rather take this over a smoothbore?

Good reamer ?

For homemade .32 or .380 chambers is this the right reamer for it? Or do i need to use one with a flathead?

Hey all! We’re in the planning stages of designing a mortar designed for use in airsoft, and would love some legal advice.

We're thinking of an idea of a blank fire mortar for MSW using 9mm PAK and from the limited research i've done regarding if this would constitute a destructive device, the ATF says no larger than 1 and one half inch barrel diameter but other than that I'm not sure what other loopholes or design constraints we will have to jump through. Any feedback or suggestions would be greatly appreciated.

Hilti powder

Hey guys,

How much Hilti blank powder do you use for each pistol cal ( important for me to know: 25acp, 32acp, 380acp and maybe 9mm and 45acp).

Has anyone maybe made a reload manual once or has a way to calculate the powder thats needed?

Can you turn rifle shells into pistol shells?

I was going through my dad's old shit the other day and found some old .22's, along with these other ones that say "6.5x55 SE S & B" (Also please tell me what these rounds are used for) and I thought the bottom part looked pretty close to a 9mm case. So I'm just wondering if I can cut them and make some.

Where to find pipes for a slamfire shotgun?

Hey all, I'm currently in the process of trying to make a slamfire shotgun in 12 gauge. I tried searching the web, ace hardware, and home depot for some suitable pipes but I either find wayyy too thin of a wall thickness or copiously expensive for some crazy amount of pipege (probably trade work). I was wondering for those who have one if they could tell me where they got their pipes from.

Also for the screw that would go into the cap, would it be better to screw into the cap or sodder it (no access to welding)
