[StillHere86]

Hello all I am seeking some knowledge hopefully yall can help. I may be overthinking this but can I use safely fire 5.56x45mm NATO XM855 rounds through a rifle chambered for 5.56x45mm NATO M193, M855, SS109 & MK262? Thanks

The 'x' identifies it as not fit for duty ammo, basically its the military's version of range ammo. It is not different that then m855 except they used to use spent brass to make it.

Sorce: took an ammo course in the Army to burn a week durring safety stand down.

No. If you have any XM855 I will dispose of it for you... Yes you can shoot it no problems.

As well as any other ammo, I suppose.

The answer you are looking for is Yes, you can shoot all that in your gun.

Any commercial or military 5.56 ammo or .223 will work just fine.

Your gun is chambered in 5.56x45 NATO, which means that it can shoot .223 Remington and 5.56x45 Nato rounds. M855, M193 are all 5.56x45 Nato rounds.

The military's version of the x-out.

According to Federal, the X designation means it was produced for the commercial market. It is produced from new components, not spent brass or rejects as many like to say. Source: Federal Ammunition and the cases of it sitting on my shelf with brand new bullets in brand new LC brass. I heard a bunch of hogwash when I was in the Army, too.

Yep. I've got some XM193 around here, same thing. Loaded mil spec, new brass. Just loaded for the commercial market.
