End of Barrel Laser for Adjusting scopes
I'm new to scopes, so I'm trying to think of the best way to zero in my scope on my 22. I want to get it as close to perfect before heading to the range. I can only go on week-ends, and with the kid and family responsibilities, time there is pretty limited.
I noticed walmart carries a laser that you can insert into the barrel, and use that to help zero in the scope. Do these work well? Are they worth it? Is there something I'm overlooking?
I'm a complete newbie when it comes to scopes and zeroing them in. Resources, tips, etc etc are greatly welcomed.
