From my experience, either of the AR based rifles (got 2) should shoot MOA or less with 168 or 175 SMKs.

The M1As (got 3) will shoot 2.5 MOA with SMKs and it takes quite a bit of work to tighten up the groups -- bedding, gas cylinder mods, trigger job.

And it is easier to mount a scope on the AR-based rifles too.
