Black Rifles RRA AR-15

[Glockrunner]

Should I be getting some blowback thru my front sight? I see it is getting fouled and didn't know if this is supposed to happen.

Dunno.
My cousin now has 6 different ARs, one a pistol. He pretty much uses his RRA exclusively.

Is your rifle a gas piston or not. Are you talking about back up sites on a flat top or a barrel mounted site?

If your talking sites mounted on the barrel...no.
