    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! This is true, as long as there are just weakly acting forces. The contact is a frictional connection only, with a very low coefficient (plastic surfaces) in addition. I meant detaching. The round openings all of our various designs enclose the cylindrical pins in a way which enables a...

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! I think the last prism mounted version will be much less sturdy regarding rotation than the 4-pin-snap-on version. These kink points of 45° won't deliver much resistance and furthermore just very few force against snapping off by accident. I'm thinking about quite another version now...

    To shape the snap on bracket more sturdy, you could place a kind of elastic hinge, like in my draft below. This would lower the risk of material fracture when bending. The thickness of the hinge could be lower than the rest of the collar (unlike my sketch shows).

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! Placing the base mount by forcing down the threadened eyepiece ring only doesn’t seem to be the best solution, as my experience with the aluminum collar shows. No matter how much you tighten the cover ring (by your finger‘s force), the collar can be turned by accident anyway. If the base...

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    A snap on mount sounds cool. Maybe the snap on part shouldn‘t be snapped on the scope‘s thread directly, due to some reasons. First, much force would be necessary not to loose it by accident and second: there would be no way to snap it right without further steps of alignment. How about an...

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! That really looks great, how sturdy are these nylon printed parts? I got no experience in 3D-printing and it's about time, I guess. And yes, I do that metal stuff by myself, using my 3-axis CNC mill and a small conventional turning lathe. My workshop still lacks a 3D printer so far...

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! The height of the outer collar is 2.5mm, the inner diameter is 54.2 mm. Cheers!

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! did You think about a turnable mounting plate? Should be easy by printing a collar with a socket at it's side (with just a hole in it) and a 360° turnable plate, locked by a screw. As it's made from plastic (PLA, ABS?), the screw will cut it's thread by itself. Cheers!

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! Sounds clever to meet these special needs! The angle of the mount seems to be fixed? I'm going to check my CAD-drawings and let u know.. The thickness of the inner collar is 1.5mm, the outer height is 3mm (oops.. maybe it's just 2.5mm, have to check that) around. The front part of the...

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! That's the point. I can either remove the red dot sight itself or detach it with the aluminum holder, just leaving the collar mounted on the scope. The alignment keeps mostly fine. The intermediate piece is just for additional height adjustments in case I'll need it. I was afraid the...

    Red-dot mounting collar for Kowa 883 Here are some more detailed photos of the red-dot sight mounting. All parts were made from a plate of aluminum alloy (AlMg4,5Mn), thickness 10mm. Planned with CAD, machined with a CNC-mill. The sight itself can be mounted and detached, all I need is a 3mm...

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    Moin! right, the threaded ring cover is used as a nut to hold down the aluminum collar. The inner diameter of the mounting collar is just 2/10mm larger than the scopes accessory thread. To mount it, you have to detach the eyepeace and cover ring, place the collar, screw down the ring and attach...

    Red Dot Sights (Reflex Sights) on Spotting Scopes

    green dot sight mounted on Kowa 883 Hi there, inspired by the different solutions of mounting a red/green dot sight to a spotting scope, I started thinking of a sturdy and adjustable mount for my Kowa w/ stay-on case. So I bought the recommended (and affordable) sight (thanks Hauksen!) and...
