Wow! I’ve used many lasers, but the 100mW Ole Mighty Green puts them to shame. The picatinny mount went right on my rifle, and with just a few adjustments of the laser it was dead on with my scope. Sighted in at 100 yds I didn’t even need the scope, it hit where ever that green dot was.
After 2 30 round magazines, the laser didn’t vary from position, unlike some lesser quality lasers I’ve had that were all over the place after just a few shots. This one holds zero, no issues.
