Borescope lasers

[One1]

I picked up a Sight Mark from Bass Pro Shops tonight because I put new Ameriglo sights on and needed to have a second reference besides grouping. It seems to agree with the iron sights and the CT laser both as far as level, but I can lay the gun over and smack the side and change the left to right alignment of the borescope laser and My CT laser from left to right. This sort of made me worry about how accurate it is. I'm sighting at 25 feet because that's about where I shoot targets at and because that's where Smith sighted the original iron and CT laser at from the factory. I was happy until I noticed the movement left to right. 

What are you guys experience with the borescope lasers as far as ACCURACY? I know people complain about the battery life and quality of the lasers..... I don't care. Just need to know I'm sighting accurately. Any experience with them?

OK I figured out the issue with the laser changing sides. It's the slide.

I have used the laser bore sighter's to great avail.

I recently built a rifle length AR15 just for target shooting and possible varmint.

Mounted a Nikon 3x9x40 bore sighted at around 15 yards-set the crosshair's in the middle of red dot.

Went to range and started target at 25 yards-dead center-never had to change zero at all.

Good to hear. I'm confident in the iron sights and the bore scope after much tests, but I'm very concerned about the slide moving enough to throw the crimson trace laser built into the gun off by as much as 3" at 9yds.
