Some of the early MLR's did have accuracy issues.
A few guys traced is back to bedding and magazine interference, others found significant roughness in the bore, a few guys re-cut the chamber and got great accuracy. Overall the barrel system was the major culprit.
The new rifles have a better 26" barrel and a new mag system and generally shoot like the should.
Compared to a Sako TRG or its competitors the MLR is a hell of a deal.
Add a match quality barrel, tweak the trigger, and it will shoot as least as well as the big name rifles...For a about 1/2 the cost.
