The 1st one I received looked really good but wouldn't cycle the action fully when firing it ...2nd one has all the issues , rear sights are junk, op rod loose , shims needed , barrel index off , even the gas lock front sight was milled on an angle . It shoots well but its a good thing I can fix all that's wrong with it myself .
This replacement Socom is my 6th or 7th m-305 and had the most issues of any I owned.
I still really like the platform but for someone not familiar with these rifles it can be frustrating.
