hi guys
i am thinking of buying two of these ,but have some doults as to if they work. here are some of the questions .
1 do's the laser work through a mod
2 are they accurate to 1inch or is it guess work

3 if these laser's do as they say ,putting a new scope on a rifle & lining it up would only take 10 mins and on shots fired .

4 as i have a shot saver already and i mark all of my rifles down on paper so if i knock my rifle i just need to put
my shot saver back on and put right .
look forward to all the replys
