Here's how to do it. Remove the battery compartment by gently prying the rear of the compartment forward and up. Remove the three batteries, drop in the washer, replace the batteries and then re-install the battery compartment. Now the rotary cam switch will work properly and positively.
Next, the spuds are easy to use, but not necessarily intuitive. First, you have to thread the bolts into the spuds. Be sure to use the longer bolts in the longer spuds - the length difference isn't very obvious until you compare them side-by-side. The idea here is to get each spud mated with its own bolt so that about 1/16" of threads protrude from the split ends of the spud. Then, you can thread the spud on the tapered end of the boresighter and the taper will open the spud to fill the appropriate bore.
As a previous reviewer mentioned, select a spud that's smaller than the bore. Then thread the spud onto the boreighter's tapered end until the taper opens it enough to fit firmly (but not too firmly...) into the bore. Once you place it into the bore and seat the boresighter in the muzzel, a small 1/4-1/2 clockwise turn will further expand the spud inside the bore to hold it tightly until bore-sighting duties are complete. Once done, twist the boresighter counter-clockwise to collapse the spud slightly so that the assembly will slide easily from the bore.
The whole unit easily pries out with a small screwdriver and one can clean the contacts and lengthen the spring a bit. This will take the vagueness out of the switch and stop the laser from being intermittent.
Also, don't use an adaptor that fits exactly. Use a size smaller and adjust it until it fits the bore properly. That means tight enough to center but not so tight it gets stuck in there. If you find the exact size without having to adjust it and you force it in the barrel it may get stuck. It also takes a bit of effort to put the adjusting screws in the adaptors (one screw for each adaptor). Once in they will stay put with the adaptor.
Finally, while this is a red laser you do not have to bore sight your gun or rifle indoors or at night. It will reflect back in broad daylight against anything that's reflective, like a traffic sign. The neighbors may think you're nuts but it works great.
Once you overcome the funky switch, it works great. Just remember you will have to go out to the range to do your final adjustments. No boresight is perfect. They just get you close.
My neighbor's workshop is about 60 yards away from mine across flat ground. Just after sundown I used this device to boresight all three rifles. It was simple -- screwed the .22-cal adapter into the end of the boresighter; jammed it down the muzzle of the rifle; put the rifle in a bench stand on the concrete porch of my workshop; aimed the rifle at my neighbor's workshop and turned on the boresighter; looked through the scope; there was a red dot on my neighbor's workshop wall 60 yards away; fiddled with the UP/DOWN LEFT/RIGHT knobs on the scope to put the crosshairs on the red dot and that was it. Maybe took five minutes and most of the time was spent screwing the adaptor onto the end of the boresighter.
Yesterday took the rifles to my son's place where we set up a bench rest then put paper targets at 50 yards and 100 yards. At 50 yards all three rifles shot within the rings with the first three-round shot group. Two more groups and we were tearing up the bull. Nine rounds per rifle to zero the sights. All rifles were dead on at 100 yards also, with slight Kentucky windage correction for elevation.
Negatives. Instructions could use a better illustration. The plastic adapters should be marked with their caliber. The on-off switch is dinky and can be turned on by sliding the boresighter into its little case. I put a piece of masking tape over the switch to protect it and keep it turned off. This device is lightweight and not exacly "robust.Read more ›
