Read instructions before posting negative reviews - LaserMax Uni-Max Rifle Value Pack

I have this mounted on a 45° offset in an A.R. 15. It works quite well in the variety of cord covers gives variable options to mount it. I have it cited in at 100 yards which is still visible in daylight through my three power optic. Regarding some negative reviews: 1. The person who questioned the durability because the laser would either stay on or start to blank, read the manual. You can alternate the setting between study and rapid blinking by manipulating the pressure pad. Study can be nice but the wrap and winking can allow for faster acquisition a greater distances. 2. As to the screws, you do need to be gentle when installing this however with the correct size screwdriver it can be done easily. A little releasable Loctite can also aid in keeping the screws in place between battery changes. Overall this is a great unit and laser max stands behind their products, so customer service is very good.
