Anyone who puts that Russian crap in their weapons deserves the jams.
2160 rounds not one jam not one fail to fire in my ‘Bulgy’ AK74.
I run Russian surplus 7.62 x 54R through my Mosin exclusively. Can’t remember the last time it jammed, and I’m using 10 round mags (with an Archangel stock).
They’re made to handle that stuff. The chambers are so loose, you almost never need to clean those things.
As a former Marine whose brother Marines were killed by AK’s, I refuse to own a Combloc weapon.
Glad I’m not running Ruski ammo. They can stick it all up there you know what. I heard a rumor Ukraine may have gazillions of that stuff stored in a mine. Might be a good time for them to dump it. An enterprising importer should check it out and if true head for Kiev to parlay.
If you have a weapon that DOESN’T shoot Russian, well, good luck.
