i believe Robert Whitley 6mm AR has already done this. in fact i believe his wildcat actually performs a.little.better. Made for AR15. Don't know why anyone would use these pretty anemic cartridges like the grendel and such in a bolt gun but they are the best it gets in an AR15. this one is a necked down grendel. case is a little bigger so a little.more.powder and a little more velocity.

224 AR
