Yep.In my experience they can actually hurt aiming. I've lined up on a wing by mistake in less than ideal lighting instead of lining up on the front sight post.
The wings are supposed to protect the front sight.
Do the outer portions of M1, HK, and AK front sights really help with aiming, or do they just protect the front post?
Wings beat hoods, IMO, since mud & snow can collect in a hood.
Collects in wings too. Fortunately God gave us fingers to clean it out and a Squad Leader to tell us what an idiot we are for dropping our rifle in the mud/snow.
Only the HK diopter sights with a front sight post ring such as the MP-5 and G-3 series "help" with aiming. Your brain can naturally aligns the circles without you thinking about it.
