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

Step 1: Off the Shelf
.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.
Step 2: I Can Do Better!
I only used the red laser once and was not impressed, I could hardly see it in daylight so this mod needed a green laser.
so I purchased one like this.
Step 3: The Rest of the Parts
Black anodised 2mm aluminium (back panel from something I took apart)
Spring from a battery holder
Various 4mm screws and bolts
Cover from a pushbutton
½” fuel pipe clip
Other odds and ends
Step 4: Mount for Laser and Woodwork
The button knob was stuck to a small square of aluminium.
I then cut the wooden block to the width of the fore end , length of the laser plus an inch and depth of laser plus ¾”.
I then marked out the centreline of the block and routed out a slot to be a tight fit on the laser, re-routed the middle section so that the laser was only tight at the front and back.
The pivot cross slot was cut to exactly the height and width of the pivot washers.
Other cuts were done for the trapped nuts each side at the front and for the adjuster at the bottom of the slot at the back.
A fixing plate was recessed into the top face at the back to slip over the wood screw in the fore end..
A hole was drilled in the side, opposite the push button on the laser and the diameter of the push button knob.
The piece of spring sits on the top of the laser and holds it down onto the adjustor.
Step 5: Adaptor to Fit Gun

Step 6: Final Assembly
second photo shows it working :)
Step 7: Adjustment and Use
The graph above shows the distances for each dot on the mildot scope.
I have shot targets from the hip with this! The laser point is so easy to see even in bright sunlight.
I have never had to adjust it or replace the battery in 3 years use.
