The holosun ls-117r is very good. - Holosun Compact Laser Sight

I had just found out how to make this Holosun LS-117R work on my Ar-15 Bushmaster Rifle with the fixed Iron Sight on the upper rail, and it also has an upgraded Quad rail on the Rifle as well. Well I took a look at the Holosun LS-117R and under the Picatinny mount there are four tiny screws that I had removed from the bottom. Then I had took two of those screws and moved them over to the right side of the LS-117 R as well as moved the Laser Beam on over to the Right side as well and then just used those two screws only. I had put the other two screws back in the box that the LS-117 R came in. Then I had tightened up the two screws with the Tool that comes with the LS-117R that comes in the Box. After that I had put the Laser Beam on and then I had tested everything out and it had worked. I had adjusted everything up with my TA-51 Trijicon Acog Scope exactly on the Red Chevron and it works just fine.
