poor barrel fit does not align properly cannot get it to work with a scope consantley changes the bubber for the barrel falls apart
Went from the mail directly into the trash. The battery compartment didn't fit and the compression spring was pulled out and deformed  DO NO BUY THIS!
I sent it back the different size bore sizes was very lose fit and not real accurate spend the extra for the price of the shells you will spend the same
That design keeps the adapters from expanding enough to fit any of the calibers I tried above. Even if you do happen to have a compatible caliber, the laser is likely not close enough to get you first shot on the paper at more than 25 yards.
Product is not well designed, power on off is awkward if not just bad. Rubber stop cracked on smaller caliber after one use, unit never fit snug so sighting was still off. It will get you sighted in on the paper but not in the target.
Laser bore sighters fits pretty good in any size barrel and has inserts to make it fit. It gives a good red laser and lets you sight you rifle or pistol perfectly. Allows you to save that over priced ammo.
I couldn't wait for the mail to get here. When it came I immediately put the batteries in the laser and tried to get the grommet to fit in the barrel. It did not work well but I believe with a little tweaking it will be exactly what I am looking for.
little trouble reproducing fit in barrel. other than that, works well. used to site in 22 cal. scope. seem to work well, must adjust tip to fit barrel ID securely. when securely fit, works well.
Answer: no
