Re: Laser Deivces Newest Class 1 IR Laser: CQBL-1
Ditto what Victor and hogrider posted.
I will add the following: When sighting in either one of the lasers, use your "far" zero distance. For example, if you have a 50/ 200 zero on your AR, co-witness the laser at 200. This will mean that you will have to do it under low-light conditions (to allow the laser to be visible at that range). However, it will give you a more accurate POA/ POI through the entire range from muzzle to 200. If you were to utilize the zero at 50, it would shift the POI on your longer shots. This is due to the slight difference in the relativity of your Optical Sight-to-bore position and your Laser Sight-to-bore position. If everything was emitted from the same point, it would be no issue. However, having the small amount of horizontal and vertical variance at the source (rifle), that difference will be multiplied as your distance from the source increases. While some would say this is negligible, I say that the increase in accuracy is worth the small amount of effort that is required. When we use lasers, we already give up a small amount of accuracy because of the size of the dot projection on target. Might as well work hard to get the most accurate zero we can so, we can quickly and humanely put our quarry down.
Be Safe,
