5.56 NATO 55gr 20rd FMJ (M193)

This is classic M193-style 5.56 NATO range ammo built for reliable function in modern semi-auto rifles. You’re getting a 55 grain Full Metal Jacket (FMJ) projectile in a brass case—a proven combo for training, drills, and general “send it” range days. It’s designed to balance velocity, recoil, and consistency so you can stack reps without mystery malfunctions.

What it’s for / why it matters: If you run an AR and you actually shoot it (not just post it), you need dependable ammo for practice. M193-style 55gr FMJ is a common baseline load for zeroing, training, and high-volume use—easy to stock, easy to run, and predictable in recoil/point of impact for most setups.

What’s included:

  • 20 rounds of 5.56 NATO ammunition (per box)

Key features & specs:

  • Cartridge: 5.56x45mm NATO
  • Bullet weight: 55 grain
  • Bullet type: Full Metal Jacket (FMJ)
  • Load type: M193-style
  • Case: brass
  • Typical listed muzzle velocity: ~3165 fps (varies by barrel length and test method)
  • Use: training, target shooting, drills, general range practice

Fitment

  • For firearms chambered in 5.56 NATO.

Does NOT fit

  • Not for .223 Rem rifles that are marked .223 Rem only (confirm your barrel marking).
  • Not for any caliber other than 5.56x45mm NATO.

Practical tips:

  • Barrel marking matters: 5.56 NATO is higher pressure than .223 Rem—if your rifle isn’t rated for 5.56, don’t force it.
  • For consistency, confirm your zero with the same ammo you train with most.
  • If you’re troubleshooting, try a known-good mag first—ammo gets blamed for magazine sins constantly.

"Ammo is more than metal and powder — it’s the embodiment of freedom. We sell freedom in brass cases. Sadly, some states fear that truth and hate freedom.

Freedom-Hating Zones: AK, CA, CT, D.C, HI, IL, MA, NJ, NY, RI — and any other state that thinks neutering the 2A makes them safer. We don’t ship there. Period.
Paperwork States: If your overlords demand permits, IDs, or FFL transfers, cough up the documents or your order dies in Valhalla’s spam folder.
Age: You must be legal age (18+ long gun ammo, 21+ handgun ammo).

We know it’s not your fault — freedom is often punished where it should be honored. But remember, rights not defended are rights surrendered. If you want to breathe freer air, everything’s bigger in Texas — the skies, the BBQ, and most of all, the freedom. Pack your bags, bring your appetite, and join us."
