223 Remington, 55gr FMJ, Remanufactured Brass, Seconds, 500 Rounds

Description

Buy 223 Remington 55gr FMJ ammo at Green Country Ammo — 500 rounds of remanufactured .223 Rem built in Texas by a veteran-owned small arms manufacturer. Each round is assembled on once-fired brass, cleaned, inspected, resized, loaded with a 55-grain full metal jacket projectile, and primed with a fresh primer. The result is range-ready .223 Rem at a price that makes high-volume AR-15 training affordable.

The 55-grain FMJ is the defining load for the .223 Remington / 5.56×45mm platform — the same bullet weight the military used in M193 Ball for decades. At approximately 3,240 fps from a 20-inch barrel (3,050 fps from 16-inch), it’s accurate, flat-shooting, and performs reliably in all .223 Remington and 5.56 NATO chambers. Feeds and functions in every AR-15, Mini-14, and bolt-action .223 without issue.

This ammunition is sold as seconds. Cartridges may show cosmetic blemishes such as surface tarnish, minor scratches, small dings, or dents that do not affect function. Some rounds do not meet first-quality visual or dimensional standards, but every round has been final sized, gauged, and is within SAAMI cartridge specifications. Seconds may be assembled from multiple production lots, so velocity and point of impact may vary. Recommended for range and practice use. All sales final.
