My reasoning's a long shot, but I'm up against something I cant explain.
I've been unable to see the front post clearly through the large aperture. It's very blurry, but then again it's perfectly in focus when viewed through the small. I still dont get that part...how small aperture's in focus but large isn't.
Anyways, one day I picked up an M4 at the shop and looked through the large aperture. Holy shite! The FP was in focus through the large aperture no matter where I aimed: lighted areas, dark areas, near, far, at the owner, customers, etc. Just kidding.
Went directly home aimed my rifle and it was blurry again.
WTF?Only thing I can figure is, my carry handle is cut and the walls of the Bushy handle somehow helped my focus. Thinking that might be the answer, I blackening my peep site and post but it barely helped, still blurry.
Any explanations? Is there a positive optic quality to a full carry handle? Unfortunately I cant remember if I experienced blurryness before I cut the handle, it was years ago when I cut it.
