I'm currently trying to work on a dust cover prototype, but can't decide on a version. Each have their pros and cons, so I decided to put it up here to see what people thought. This dust cover would go on top of the actual dust cover, since the return mechanism is riveted there and would end up really complicated to manufacture. Also, all versions feature a ramp for brass ejection.
(Please keep in mind that version 1 is the one I spent the most time on, 2-3-4 are quick mockups I did from version 1 in 10 minutes, they would have a better look once finished, not just square angles everywhere)
1. 2 top rails, the front one that co-witness with the iron sights. Full see-through for iron sights. Cheaper as the top rail is bought separately. It has another optional side rail on the left too.
2. Even cheaper to manufacture, as it keeps the original (or aftermarket) upper handguard. Could end up looser (wiggly) depending on upper handguards. Also has an optional ~6inch side rail on the left.
3. Full length, but the top rail has to be machined with it. It would cost more and the iron sights could end up difficult to use for longer shots. Also has optional side rails. The end part (near the muzzle) would probably be visually different, most likely to line up with the lower handguard with some other detail cuts.
4. Full length, also the top rail machined, but it loses the iron sights. Lighter, but less versatile and still more expensive than 1 & 2. Same comment for the visual look as 3.
