Want to give your AR-15 a thousand rounds of 5.56x45 NATO ammunition? Say no more. This ammo was made for Federal at the Lake City Army Ammunition Plant, and it evinces the same exact quality as the cartridges you would get for free if you just sign a little paperwork at your local U.S. Army recruiting office.
M193 is the designation for the basic 5.56 ammo issued for field use with the M16A1 rifle. Federal puts an X in front of it when the ammo is going to the civilian market and not the U.S. Armed Forces. As such this round has a 55 grain FMJ bullet loaded to a standard muzzle velocity of 3,240 fps. This is a perfect bullet for target practice – completely steel-free, for compliance with any range’s policy on magnetic ammunition – and also befitting of a home defense situation. That FMJ’s going to splinter apart if it hits soft tissue at about two-thirds its muzzle velocity.
Military-grade 5.56 ammunition’s cases are brand new, made of brass and reloadable several times. You will notice that their shoulders are discolored, which is the natural and strictly cosmetic product of the heat treatment which made them stronger. This Boxer-primed ammo is bulk-packaged in a giant 1,000 round box.

Q: How is the accuracy with this shells with a 1.7 twist barrel
Posted On: 5/11/2022 By: Barry
A: Thanks for reaching out Barry! That's a great question. You may or may not already know that our Army's M4 carbine also has a 1:7" twist rate, and this right here is the most basic kind of 5.56 ammo that's issued for field use with the M4 carbine. Now, I know nothing more about your rifle than its twist rate, so I can't promise any degree of accuracy. That said, you can expect reasonably good accuracy from Federal American Eagle XM193 (which is not match grade by any stretch of the imagination). I would estimate that a competent marksman would get 3" to 2.5" groups at 100 yards with this ammo and a 1:7" twist. An exceptional quality barrel, a good optic and a skilled shooter could possibly narrow that down even smaller.
