I'd ask why you don't have wrist weights instead
Homemade weapons thread
Wrist weight would make excellent handload devices as well but wouldn't be as good a blunt instrument as the dumbbell.
True, but they're easier to explain than dumbbells when you're out and about
I have coronary aneurysms. So because of a hear cath picture that was taken at the age of 5 I have a get out of jail card, for is I do shoot somebody.
Being on blood thinners helps as well to make a case of why I should be able to escalate.
I can say that I was afraid of bleeding to death, or having my heart rupture because of physical violence.
As I understand it, you are basically inserting a steel rod into your barrel that seals the walls off, expect for the places you want the rifling to be. Then you pump salt water through those holes and hook it up with a weak electric current. This makes the metal rust away in the spots where it actually contacts the water, leaving you with a very shallow rifling.
Looks easy enough, and very easy to reproduce reliably. Making the insert would be the hardest part, and the fag in the link you posted (as well as his sources) use 3D printed inserts. You could just take a rod with a rectangular cross section and twist it to get the same effect.
thats not what more common means
Just fry my brain up senpai
Shit's not that hard, user. You're looking at the tip of the iceberg.
You forgot recoil system.
