Nope. That's a common complaint, and I have the same issue as well with my gen II. Most of the buffer tube covers I've seen are too thick and just make it worse.
There's a few homemade solutions but no one's making an aftermarket option. I've seen pics of someone notching the top edge of the rear peep sight but not sure what they're doing for a taller front sight.
I found a pistol sized reflex sight on a tall riser with a QD mount to be the best solution for me. I can still use irons in a pinch but no fun for range use. It sits quite a bit higher than the irons so they're blocked. I did replace my front post with a KNS crosshair sight, for me it speeds up target acquisition which means less time looking thru the irons. I also just added a Blitzkrieg chevron front post on one of my ARs, also a good option for speed.
BTW I read on another forum someone else tried adding a KNS crosshair and they couldn't lower theirs enough to zero @ 25. Mine does but it's bottomed out, and it's the flat (not hooded) version, which is thinner.
Midwest Industries has a swingaway side mount for a red dot but so far I'm not impressed with the reviews, doesn't sound like it's as solid a mount as it should be. I've also seen 45 deg offset sights used but unless they're flush on top your Sub won't lock up when folded.
