This ammunition generates insufficient gas pressure to cycle a standard AR-15 system. The manufacturer recommends this ammo for the following:
1. Bolt-action rifles
2. AR-15s with suppressor-optimized uppers

The speed of sound? You’re looking for .223 Rem close-range precision target ammo with a muzzle velocity *well below* it. Something that reduces report to less than 125 dB in conjunction with a suppressor so you can enjoy a *uniquely* quiet range day. That means you just found exactly what you want!

Atomic Ammunition loads excellent stuff in Phoenix, Arizona. This hand-inspected ammo features reloadable virgin brass cases, exactly weighed propellant charges, and, most noticeably, 77 grain hollow point boat tail projectiles. The aerodynamic and balanced non-expanding projectile supplies nigh-flawless accuracy at *close* range. Keep it within 100 yards, and you’ll be just as impressed at this ammo’s precision as you are by its gentle report.
