"The SMR is designed to fit M4 Carbine mil-spec flat top upper receivers and must be used with a low profile gas block (such as the Geissele SGB). Upper receivers that are not mil spec such as those manufactured from billet may need to have gunsmith modifications made to the SMR to fit properly. Compatibility with gas piston systems is unknown at this time (May 2013)."

it's forged, not billet, and it is mil-spec. nothing in there indicates that it wouldn't fit.
