Loaded on ten round stripper clips, these are ideal for loading AR style magazines with the appropriate guide, and for use in training, target competition and civil defense roles.

Founded and still based in Anoka, Minnesota, Federal Premium ammunition has provided high quality ammunition for use in sporting and defense applications since 1922. Provided with commercial grade, boxer primed cases, once fired brass by Federal remains in high demand among reloaders and range hosts for reuse in competition ammo. This 420 round case is perfect for training, competitions or just keeping on hand for whatever happens to be required.

The 5.56 NATO cartridge was built upon the successful .223 Remington yet loaded to higher pressures. It should not be loaded in .223 Remington chambers, even though it will fit and fire. The 5.56 remains in military service despite efforts to replace it because of its economy and effectiveness at close to medium ranges. It is also comparatively controllable in full auto for such weapons. This hints at what is another feature that many shooters enjoy and that is its negligible recoil.
