Aguila 1E556125 Green Tip M855 5.56x45mm NATO ammunition delivers the penetration and reliability that military-spec rounds are built for. If you're running drills at the range, training on steel, or stocking up for serious 5.56 practice, this 62-grain full metal jacket boat-tail round gives you dependable performance in bulk. You're getting 300 rounds per box with four boxes per case—enough to dial in your rifle and build confidence without constant resupply runs.

The M855's design centers on a copper-jacketed steel point that resists deformation under impact. That hardened tip lets the round penetrate effectively and maintain velocity through barriers and distance before tumbling or fragmenting occurs. It's the same engineering that makes M855 a go-to for high-volume shooting where consistent, deep penetration matters. This is ammunition built to perform, not cut corners.

Whether you're working through a dedicated training block, running carbine classes, or simply need reliable 5.56 ammo in quantity, the Aguila M855 case buy makes logistics easier. The lead core and steel-tipped construction mean you're getting genuine military-specification performance without the military price tag. Load up a case and focus on your marksmanship instead of wondering if your ammunition will hold up.
