Some of you are behind the times my friends. There are some laser bore sighters that can level the cross hairs. I did not say that it will level the gun.
You guys are misunderstanding what I`m asking. A level that I`m looking for will make sighting in a lot easier and it will make the scope perfectly level with the firearm, which is what the a boresighter will not do. If some of you are happy with eyeballing, fine.
LongRifles, yes I know how to sight a gun in without a bore sighter. But, there is a faster way without wasting a box of ammo. Just like one said, the bore sighter will get you on paper or very close to zero.
Thanks, a couple of you gave me the answer I was looking for.
