i never knew the SA-M5s,. or at least the Bulgarian 5.56's where actually in service anywhere!
thats pretty kick ass.
the SA-M5 is almost identical to a SA-M7,.. except that they are chambered for diffrent calibers.
and the magazines are shaped diffrent.
my SA-M5s(no-ban) has had a case and a half of the 62gr. Wolf FMJ thru it with not a single failure of any kind as of yet,...and thats only with two cleanings
Arsenal makes one of the absolutle best milled rifles,...you more than likely will never have a mechanical problem with one of there rifles,...now if you get a Arsenal that was made in Bulgaria,.there may be a issue with the finish comming off with some of the solvents and cleaners used here in the states,...but if you get one made here in the ststes,.. like mine was it will have a superb finish that will stand up to almost anything.
and if you are thinking of getting a SA-M5,...and you have a line on one,.. i would recomend that you get it without delay.,....you wont be disappointed.
