Feyachi PL-19 Red/Green Laser Sight Upgrade Airsoft Gun Lasers Low-Profile Compact Red Laser Sight with Picatinny/Weaver Rail for Pistol Handgun Rifle Shotgun

For the price especially, this is a knockout. Fits rails well, - added a little threadlocker just to be sure. Laser brightness (red) is fine and adjustments are intuitive....with hex wrench included, yet! Very happy!

Works perfectly

I've never bought a laser sight for a gun before, so I opted for one that was affordable to dip my beak. This was so easy to put on, looks good on my pistol, and works great. Now I don't have to decide between blurry target and clear sites, or blurry sites and clear target........I can just look downrange at the dot and go. The price for what you get is also fantastic, and they even included a couple sets of batteries! Now........about that. I had to ding it a star because it drains batteries even when it's off, which makes zero sense, and partially negates one of the main purposes of getting a laser sight, which is the ability to defend your home in the dark in case of an intruder. Since you have to remove the batteries to preserve them, you are basically stuck with only putting them in when you are "planning" on going shooting. Not very practical to have to load, rack, AND install batteries when the baddies bust in at 3AM (God forbid!). Otherwise, a very good starter/intro laser for your gun that's small and doesn't burst your wallet.

My rails are a bit too narrow and can easily get knocked or falls out. But it did fit a different pistol.

Worthless. It connects fine to the rail and the laser works. However, the laser isn't even close to where the pistol shoots.

I don't have any idea why I bought this! I installed t on my PCP Rifle and said how bad can it be. I set the laser by eye at first to at least bring it in line with my rifle. Then I tried it at 25 yards. I had to bring in the aimpoint a little bit more but EVERY shot was in the center ring!! I popped it off my rifle put it on my Sig Saur 9mm and without any adjustments at 30 feet, i was getting the same results! for a cheap little laser sight this is phenomenal!

I ordered four of these little lasers. Each came with two batteries. Half the batteries were DOA which made other troubleshooting more time consuming. Of the four I ordered, two worked great. Zeroed easily and held zero even on a 12 gauge and a .223. The zero adjustment screws do feel very loose, but they held zero. No complaints and the lasers were visible >25m. The other two were a different story. One of the two defective unit's elevation and windage screws had no effect. The other defective unit simply would not illuminate at all.

great
