This is the famous and hard to find mil-spec M855 steel core 5.56x45 ("green tip") penetrator ammo you have heard about! It is loaded to NATO specs and is NOT intended for use in commercial or bolt-action rifled chambered for 223 Remington ammo - but is is perfect for your AR15!
This product is brass-cased, Boxer-primed, non-corrosive, and reloadable.

Cleanliness. I find this particular ammunition to be a middle of the pack performer in the cleanliness department. You will likely not be impressed nor disappointed by this round’s fouling effects.
Accuracy. The vast majority of my 5.56 shooting is conducted in relatively short distance training scenarios. However, accuracy testing is part of the regime through which all my training ammunition is evaluated. The tactical optic on my primary testing rifle (the Tavor) has a 3.5 MOA red dot. For those unfamiliar with this terminology, that means that at 100 yards my aiming point is not a set of fine precision cross hairs, but an approximately 3.5” red circle. This is an acceptable accuracy trade off in exchange to gain rapid target acquisition at closer ranges. Despite this long range accuracy hampering draw back of the chosen optic, I am pleased to report that at 100 yards, this particular rifle has averaged approximately a 2.6” collective grouping across the 11 brands/weights of ammunition tested thus far. The Winchester M855 has averaged approximately 4.9” in testing. As a comparison, the American Eagle/Lake City M855 has averaged approximately 5.2”, which is not a significant accuracy difference in my opinion. These disappointing numbers appear to be an aversion to M855 ammunition in general, not the 62 grain weight. This is based on the fact that the best accuracy was consistently achieved by the 64 grain Winchester Power Point hunting round. (Posted on 1/26/16)
