Mega MKM Rifle Length question?

[Army203]

Would any of you know if the Mega MKM rifle length upper allows room for a standard sight base on a 20" barrel? I don't mean the extended rifle key mod, but just the standard MKM rifle length. Thank you for any help.

Just spoke to Jason Curns at Mega. A rifle length MKM will fit behind a 20" barrel with a FSB.

Awesome! I love it when a plan comes together.
