Mrtravell Red Dot Laser Sight 20mm Standard Picatinny Weaver Rail Mount for Pistol Handgun Gun Rifle with Two Sets of Batteries

Easy to install and site in . Works well so far . I may get another for a spare .

Product don’t work!!!!!!

the picatiny was just a little longer than what I had hoped for .. looking to put it on a micro gun like my sig 365 ... too long for that ... that's what I searched for when I found this .. nice little site for the money ... gonna put it on another gun..

It fits my S&W M&P 45 perfectly. It is easy to site in as the adjustments are easy and exact.

My only real complaint is that when adjusting to zero in, one screw is supposed to be windage )left and right), and the other up and down.. but when I turn one, it moves both side to side and up or down.

should come solid

I have not use it, but I played around with it. It seem to be working just fine. 4 star because no use as of now.

Does not seem to stay in aim when firing. Switch came loose and would not turn on anymore without tinkering. Cover for internal components crept its way out while firing at the range. I removed it from my weapon and use it for other purposes now.
