Nc star 1x40mm tactical red dot sight with laser - NcSTAR 1x40 Red Dot Sight w/ Built in Red Laser-QR Weaver Mount

I purchased this several years ago, mistakenly thinking it would work on my home protection shotgun. It was hard to zero, then once on, it would not stay. It's off the gun(s) and in the closet. I may try it on an airgun just to get some use out of it.
Cons: Will not hold zero
