I have a Tech Force 4-12x40 AO Rifle Scope, Illuminated Red/Green Duplex Reticle, 1/4 MOA, 1" Tube, and I wanted a sunshade for it. I looked, but I could not find one on the air gun websites. Maybe I didn't look hard enough.
Anyway I took a chance with this 40mm sunshade, and it fit: Mueller Optics 40mm 3-Inch Sunshade - Black SS340
If you have the same air rifle scope, or have a similar 40mm scope, and looking for a sunshade this might work for you. At $10 it is worth the try. I can confirm that it fits the Tech Force 4-12x40 AO Rifle Scope, Illuminated Red/Green Duplex Reticle, 1/4 MOA, 1" Tube.
