When I first tried out the alpha, I thought this was a really neat idea. Offer an alternative to stock iron sights that doesn't cost any supply. Even if your chosen weapon has crummy irons, you can throw on flip-up sights to get a better sight picture (Though still not as clear as a 1x optic) while still saving that precious supply point. Which is why I'm kind of confused about the decision to raise the supply cost to 1.
Doesn't this kind of make flip-up sights irrelevant, when you can have a 1x optic like the holographic for the same cost?
As a side note, would it be possible to make the ring on the MP7's flip-up sights a little thinner? Right now, it offers a very cramped sight picture and doesn't make for a very good alternative to stock irons.
