The M22 does come in the Phoenix and it's a single shot. It's the .308 group. The Phoenix has a wider stock and is good for benchrest... or so I was told. The M52 has a detachable, single stacked 3 round magazine ( I believe) and the Phoenix stlye synthetic stock called the Jackson Hunter. It's narrower and destined for the woods. It's the .30-06 group.
