Compact Tactical Red/Green Beam Laser Sight,Laser Dot Sight Scope for Rifles Pistols Handguns fits Standard 20mm/11mm Picatinny Rail Mount

Great scope. It fits well, very durable and the visibility is awesome. Great value for the money with a long lasting battery.

Fantastic beam!! its to easy to slide down the barrel and comes with allen to lock it down and fine adjust the aim. Far as battery life I have used it for 4 months 3 times a week, still strong.. for the price great value

Great fit although it took considerable micro adjusting to sight it in accurately.

This review is for the Mosandon red and green laser pointer gun sights. The RED laser is invisible in sunlight. It's bright indoors and faintly visible in the shade - and that's it. There is no possible way this could be used outdoors in daylight. The GREEN laser is more visible but still not good enough in sunlight. And literally everything else is wrong. First and most amazingly: the laser housing is too narrow to be held by the mounting clamps, on both the 11mm or the picatinny rails !! Look at the picture here which shows that with the clamp tightened on the 11mm rail there's still a huge gap on both sides of the sight housing! So the sight just rattles around loose! And the same is true with the clamp flipped over to use the picatinny rail. Incredible. Using some metal shim stock and I finally got a tight grip on the picatinny rail so that I could at least try the sight. Then I found that the adjustment set-screws move against almost no resistance, so the settings continually change while shooting. The point of impact will drift further away with each shot - while aimed at the same spot. Soon it's inches away from where it started, at a 20' range. It's baffling to me that a company will make a product with multiple deal-breaking flaws, all of which could be easily avoided or corrected. Then you'd have a usable gun sight well worth the money. Instead, *every single one of these will be returned*.

High quality

The laser pointed way off to the right and up. The adjustments made little difference. I used the Allen wrench to manually adjust the sighting by placing is down the laser hole and adjusting it that way. Got it centered, but doubt it will stay in place for long. Avoid if possible and look for alternatives.

The sight was easy to install, looks well built, and works out well on a 22 caliber rifle. I don't know how it would do on a high caliber one. It shines brightly in the sun at 30 to 40 yards. I would buy again.

Works gt
