Kristie,
The original BM59's were made with original Garand receivers, bolts and most other parts. Only the barrel and some other parts so the detachable magazine would work were different. Later ones had Baretta made parts with quality equal to original Garand parts.
Some of the 7.62 NATO loads used in military issued match grade M1 and M14 rifles produced virtually proof load pressures (67,000 cup) without any function or reliability issues whatsoever. Better accuracy than M118 and M852 match ammo.
