Winchester Ammo WM855K USA M855 Green Tip 5.56x45mm NATO 62 gr 3060 fps FMJ20 Bx/50 Cs

Winchester USA M855 Green Tip 5.56x45mm NATO ammunition delivers the reliable, no-frills performance that keeps shooters fed at the range or in the field. This is the classic military-spec round—62-grain full metal jacket projectiles loaded to 3060 fps—designed for AR-15s, M16s, and other 5.56 NATO platforms. Winchester's White Box line has earned its reputation for consistency and value, and the M855 is the workhorse that proves it. Whether you're zeroing in, running drills, or stocking up for serious volume shooting, this ammunition runs clean and groups true.

The 62-grain FMJ bullet is the NATO standard for a reason: it cycles reliably, penetrates well, and shoots flat enough for mid-range precision work. At 3060 fps muzzle velocity, you're getting honest ballistics and 1289 foot-pounds of muzzle energy—enough thump for target shooting or training without excess recoil. The full metal jacket design keeps your bore clean and is non-magnetic, so it runs fine at most public ranges.

Sold in bulk (20-round boxes, 50 per case), this is ammunition built for shooters who burn volume. No fluff, no premium pricing for marketing—just Winchester's track record of making ammo that works. Pack a case for the range, competitions, or long-term storage knowing you're getting consistent, field-proven rounds.
