Switchblock and Mega Mono Upper

AR/M4 AR Technical Discussion

Anyone tried installing a Noveske Switchblock with a Mega carbine length billet upper?

I imagine since a standard gas block would be exposed that the Switchblock would fit but I want to be sure before I drop $550 on an upper.

Thanks all.

If a fixed front sight will fit then the Switchblock will fit.
