Tipfun Bore Sight for 357mag/38spl Special Red Laser Bore Sighter Red Dot Boresighter with Batteries for Hunting and Shooting

I've bought three different calibers lasers. None have failed to work. They are range limited, 25-40'. I found that they work the best in a daylight lit room in your house. they will get you on paper.

Enabled a one-shot zero at 50 yards. My first shot after zeroing was 1/2 inch off, a very good result.

Easy to use got my red dot on paper

The fit is good, without any slop or play; the laser is bright and seems consistent when the casing is rotated 180 degrees (meaning the laser seems well centered in the brass). I got everything I expected; however, i took one star off for the inconvenience of having to install a battery current blocker inline with the button batteries (a plastic tab) to shut it off; a quarter turn on/off switch would have been preferable and would have pushed this to maximum.

Batteries were dead! Makes you wonder how long it had been sitting on the shelf and why wasn’t it checked before packaging. Nothing like this should happen today.

Great tool to help with sighting and saving ammo.

great item easy to use and works great well worth the money

This Red Laser Bore Sight works well for me, to pre-align rifle Sights/Optics, prior to going to the range, where final adjustments can take place.
