Excellent laser for the money - SightMark SM25016 LoPro Mini Laser Sight Green Laser Picatinny

My first impression was that this is a well-built laser. It does not feel like most of the cheap, sub-$100 lasers. It mounts securely to the Picatinny rail on my Aero Precision handguard and has not lost zero in 600 rounds. The remote cable switch is easy to use and is more tactile than flat pad type switch on many other laser sights; I just wish that the switch had some way to mount it to the rail. I ended up using some industrial grade Velcro and it has remained in place so far. The green beam is bright and well focused. This laser won’t be mistaken for a military-grade Steiner, but it doesn’t cost $800+ either. I would definitely buy again.
