it was a fairly clapped out Greek M1 parts kit cheap off the DCM catalog years ago. barrel was trash, a lot of the furniture was "okay" and the receiver and most small parts barring some pins or springs were also in good condition. some refinish and NOS and a new criterion barrel and it's an excellent tanker black tail or big horn sheep killer for those 200+ meter hilly/mountainous shots up around Shasta and the Cascades where i typically use it. i also keep a .300 RUM build on a 700 action if i anticipate moose or something.
it was included in the 1934 national firearms act in the US due to (in part) efforts to curb organized crime through tax evasion laws which primarily was held to target machineguns and handguns before morphing into other things. "silencers" or suppressors were included not because they were used frequently by criminals at the time, but because of their potential use in crimes. after that, it was very very hard to remove them from the NFA (as it is almost always very difficult to repeal established law) over the years. the entertainment industry does not help this view in the public with their "pew pew silencer go brr" type action scenes in the hands of assassins, et c.
