It would come close, but the M27 rail is shorter then the rail used on the Infidel. If you wanted the *exact* same look, you'd have to shorten the barrel slightly to match.
I have no problem with that. There is even logic in it:Before the release of the MR556, people were trying to make an AR look like a HK 416. Now that the MR is out, people are trying to make it look like another AR. Seems like we've come full circle here
