Nothing beats Mk262 Mod 1!


There's nothing like it for a factory load. This is the real deal military spec Mk262 Mod 1 ammo packaged for civilian sale. This ammunition performs better than any other factory loaded 77gr ammo in all 3 of my long distance 5.56 SPR's. This ammo does not disappoint!

Bad experience

by -

Primers coming out of brass causing gun to jam.

Great mk12 food

by -

Works great in my mk12 with 1:7 5.56 Douglas barrel. Produced a .507 group at 100 yards under less than ideal conditions. I know this ammo and my rifle are capable of better. Will buy more. Also wish I could add pictures, but the group could be covered up by a dime.
