My Umarex Fuel ate the scope it came with alive. I replaced it with a Center Point 4-16×40 AO scope with illuminated reticle. I’ve been shooting with that scope for about a year now, and several thousand shots later, it has held zero flawlessly. The other day, however, I went to use the illuminated reticle and here’s what I found:
The dial to control the illuminated reticle had its screws vibrated loose from the recoil of all my shooting and was just hanging by the wires that went to the illuminator. I carefully disassembled the dial to get to the screws.
Note the ring on the bottom right. I used a small screwdriver to rotated it out of the housing. The round circuit board came out from underneath it. Here’s a view of the dial with the above components removed:
I then removed all six screws seen above. This allowed me to remove the dial, exposing the three loose screws.
To hopefully prevent this from happening in the future, I applied blue Loctite to all screws as I reassembled everything. After 24 hours, it should be ready for several thousand shots more. In the meantime, here’s a view through the scope after reassembly:
In case you haven’t seen it already, here’s a video showing how you can make a scope to cell phone adapter for any phone you can get a hard case for:
