Thank you all for your comments.
Max H. I will keep in mind the possibility of interference with/from my spectacles and go and try a sight at my local gunshop.
As for the 6x Acog Murphy, that would appear to be better mounted on a military grade .50 calibre rifle, than a light weight air rifle for close range pigeon shooting! You would certainly do maximum damage to the pigeons though, not to mention the surrounding countryside! I guess the pigeons would be well plucked after impact!

Interesting topic, all the red dot scopes I've used in life seem to cover to much to shoot tight groups. Can you buy one that is only 1moa!
Most I can find are 3-5 or even 6 moa. That covers to much of the target for me. If 1moa is available then it would seem that 1/4" at 25 yards is still big but entirely usable. I have a webley Alecto that would love this type of sight!
To be fair to the sighting system they aren't really designed for shooting tight groups they are meant for rapid target acquisition and getting shots onto target.
With practice though they can give very good results. I find the sights that have 2-3 MOA dots are very useable.
One of the biggest things I find is that the dot should be crisp and well defined, a lot of the cheap end red dot sights are more red splodge than a dot.
People who have been there focus on the fundamentals. People who sit at keyboards all day focus on the trivial and inane.
Have tried two, one was a two stage bright for daytime, but dim for night, open tube so could shoot with left eye closed, found it easy to accquire targets, other was OEG, made by Webley, needed both eyes open and enough light to illuminate dot, cleverly gave small dot when close to eye on rifle, but dot appeared to increase in size when further away on pistol. Found it difficult to judge range and holdover compared to scope, but if used in ambush from known range worked well. IMHO. David
Many of the difficulties that people have with such sights, are due to the dot being too bright - simply turn the intensity down a bit...
one more thing to remember. some people think of red dot as lazer. it aint.
the only thing i can find wrong is the nut on the steering wheel.
I've tried a few over the years, I've gone back to low mag scopes, but I don't have anything particularly against them either. Get a cheap one & try it out is probably the best thing to do. My only peeve is they pick up reflections from behind, & as I was shooting in barns with a lot of naked lightbulbs around, I occasionally shot at the rat with the wrong dot.
