Why must we use the M16 sight?

[Oskar]

Thanks but the M1 Carbine looks a bit odd so im working on 2 other verisions, one with Folding stock, the one the airborne used. The new verision looks gooder i can promise

I believe the reason is no one has made any new sights. Well I've been working on a M1 Garand sight, and (seeing as I've never looked down the barrel of a real M1 Garand) I'd like your opinions on it.

Dont know if answered but
I looked at a M1 Garand last time at the range and it looks much like the m16 one so just change the left and right part of the rear sight a bit and its done
