200 Rounds of 5.56x45 Ammo For Sale

200 rounds of 5.56x45 NATO is the half-day-class quantity for AR-15 shooters - enough to cover a typical carbine course, weekend match, or back-to-back range visits without dipping into your bulk reserves. It sits between the trial-size 150-round packs and full 1,000-round cases, hitting the volume most shooters actually burn in a single training cycle.

5.56 NATO ammunition is the military-spec build of .223 Remington, optimized for the AR-15 and M16 family of rifles. 200-round packs from major manufacturers typically feature M193-equivalent 55gr loads (the original military ball spec) or M855 62gr green-tip loads (the steel-penetrator follow-on). Both feed reliably from standard AR-15 magazines and shoot to typical factory zeros.

Why buy 200 rounds of 5.56

• Class and match quantity: covers a standard carbine course round count.
• Volume pricing: per-round cost beats 20 and 30-round boxes.
• Practical reserve: meaningful supply without full-case commitment.
• Storage-friendly: fits a standard 50-cal ammo can with room to spare.
