I have a 556 with a LW barrel that shoots under 1 moa. I put a Osprey Defense piston on it. I thought I would loose accuracy but it was not the case. I did not even have to work up a new load for it. It is a different piston system then the adams.
Maybe I just got lucky. I have not been willing to put a piston on my grendel although I am still thinking about it.
