I have a older AR 15 with a regular A2 front sight. I put a nicer quad rail forend on it. I want to put a reflex type sight on it. Of course the A2 sight stands up in the way. I have a Mbus rear flip up sight now and it is sighted in with the existing A2 sight,
Anyway, I want to replace the front gas block to a low profile. Do I need to get one with short rail on top (to mount a flip front sight) or can I just put the flip up front sight on the end of the forend quad rail. It goes right up to the A2 sight.
I was not sure if the distance between the rear sight and front sight was that tactical?? (it is carbine length if that matters?)
Hope this makes sense
Thanks
