/diy/ - Do It Yourself

I agree, if you are going to build a toy gun, why wouldnt you just build the barrel too?

>Rifling is tough because they either didn't bother or used very specialized machines that are extremely rare and expensive now, which is why I am trying to find a way to do it on the cheap.

Look up "rifling buttons"
They are form tools. You ream your barrel, then you press the button through the barrel. It spins on its own, forming the rifling.

Its cheap and quick, and any non "hammer forged" barrels are pretty much buttom formed.

You can buy chinese buttons for like $15 on amazon
