Air rifle laser sight

This mod to my airarms S200 was acomplished with little more than a drill, a router and a few hand tools.

Design criteria:-

1) As few mods to the gun as possible (I got it down to 3 wood screws)
2) Easy to adjust (1screw with a spring to return)
3) It must stay in alignment (After fitting I have never needed to readjust it)
4) It must look like part of the gun

Like a lot of air gun shooters, as soon as I saw laser sights for sale I had to have one. What I purchased was a small black module with a choice of mounts, dovetail and scope rings, it contained a <5mw red laser a couple of button batteries and piece of wire with a pressure switch on the end.

.I first mounted it on top of the scope lined it up with the 3 fiddly little screwdriver slot screws put it in the soft case and went shooting. As soon as it was out of the cover I could see that the laser had moved…….I will not bore you with all the ways I tried to make this useable.

so where did u get that graph. I've been looking for one like it. This was exactly what I was looking for. Job well done!

I set the rifle up in a clamp then fired at a target, noted the laser position and pellet hole, then moving the target 5m further away between shots recorded my two series of data.
It is neat isn't it! :) It makes rangefinding a doddle.

This is very cool, for the daytime. Now let me share a little project I did when I needed to eradicate some raccoons during near total darkness, as it was very similar to what you did here:

Instead of using a 'daylight' scope, I used a "Thousand Trails TM" night vision hand held 'starlight' scope that had no reticle and retailed for about $125. I then attached (using screws and epoxy) a rail mount to the scope so that I could attach it to the rifle (a CAR15). I then installed a weak red laser (so don't throw away your original) which became the reticle for the night scope (as you could see it quite clearly through the scope) and to help enhance the image in total darkness, I also added a "Surefire" high intensity flashlight with an IR filter made of 2X blue, 2Xgreen and 2X red filters from the old "bent neck" US military flashlights.

Let's just say that the 'varmints' are now history.

I hope you can use this little bit of info for your next firearm project.
