A friend and I have been looking at these calibers/caliber for awhile now(358bfg/358 gremlin)...awaiting some word on them in an AR platform. My friend has been in contact with a couple of folks about them but keeps getting the call me in a couple months run around...the last post on a build was early 2011 from what I found here. Does anybody know... does it work in an AR or not? Just looking for some good facts. I think it would be a great gun to play with and I all ready have the grendel.
