Great laser sight for ars or pistols - LaserMax Spartan Adjustable Rail Mounted 5mW Red Laser Sight

I purchased 2 of these for just south of $200 and free shipping. Easy to install and set up. When I received them, one did not work, not even after trying a new battery. OP quickly gave me an RMA number and exchanged it at no cost. Been doing business with OP for years and I shop nowhere else for my optics and sights. Great prices, service, and product selections. It's a "no brainer" for me.
The green lasers do get lost in bright sun light at better than 20 yards. So dim it is hard to see, at least mine are. Closer than 20 yds. and they are spot on. I mounted them on my Taurus PT 111 "Truck gun" and Ruger American Compact "Coyote gun" and they fit the underside rails like they were costume made for these pistols. I even mounted it on my 556 AR for about 500 rounds. I wish they were still on sale, I'd purchase 2 more. No trouble with paddle on/off buttons when in my holsters or carry bags. So far, they are holding zero, and for daylight close up aiming 20 yds. or less, I just put the dot on my target and fire. Don't use the sights. Great little additions to a pistol, especially when you have 70+ year old eyes.
I wish changing out the batteries were easier, hate to dismantle and then reinstall, but it is what it is. Maybe LaserMax will redesign the battery issue on the newer version, and while they are at it, remove the on/off paddles and use recessed push buttons like the model made specifically for the Ruger SR22. The SR22 model can not be accidentally turned on in a holster or range pouch, but the controls are just as easy to operate as the paddles. I think the recessed buttons are better and more ergonomic to your shooting hand. Been doing this a long time, and sometimes the simplest way is the best. Can't go wrong with the LaserMax Spartan.
