has anyone made a ar15 out of a metal bb/airsoft lower? if so what gun did you get? difficulty scale?

Anyone been brave enough to convert one yet ?

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

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

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

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?

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

Can something other than bullet striking a baffel cause tumbling?

idk how lol

Like the one in this video https://youtu.be/Jvv8f_bQnSk?si=VlXF4xvgwBo8TvIm

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.

So i'm planing to build a 7.62 rifle, but idk where can i get the barrel since these are Made from an special steel

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?

I've ordered enough tubing, wood, etc. To make a pistol and rifle. But, I don't really know any rifle designs. Does anyone know any??

I

I'm from Australia and idk where to look for parts. Someone pls help me

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.

Shit held together by tape, Guns made by crackhead etc Looks like it's been made by a 5 Yr old etc

Yeah this is a troll post, Did it for the sake of karma. Firing test coming soon
