Is the Ruger American 22-250 flush fit mag an AR platform? It may not fit the action lower of the 6.5 Grendel RAP. (Unless you change out the bottom metal or actually plastic in this case), between the two rifles. The case diameters are close enough between the two cartridges to warrant an experiment. Please do give us an update when you get your Grr RAP.
