Ok. Kinda thinking too hard so thought I would ask. Since I know lots of members here have cans.

Alignment rods. I’ve seen the cheap diy options and still sorta up in the air about that. I haven’t looked hard but seen a few from 30-70 a pop. Humm.

Are they really needed ? Heard the old trick is to just look down the bore against a wall or something..But ?

223,308,6.5 and 22 rimfire are the calibers I’m throwing cans on for now.

Opinions? Options?

I’m all ears....
