Looking for a decent bore laser

[bearfutedninja]

I recently swapped a bunch of optics around and need to get them sighted in. Anyone reccomend a good bore laser. I need one for 22 9mm 556 and 308

I’ve tried probably 6 or 7 different ones and honestly none of them are good. Some will get you on paper but none of them actually did what they were supposed to do. I’m also interested to know if one exists that’s worth while
