Questions & Answers
What’s the difference between these and the “green tip” M855? Expert Answer

These are just a 62 grain projectile and m855 has a steel penetrator inside of the round.

by Ben, Gear Expert, June 17, 2021
Are these allowed in indoor ranges? I know they ban some kinds of ammo at some places. Expert Answer

That is entirely dependent on the Range, you will have to reach out to your local ranges and ask them.

only for 5.56 by Angelo, February 22, 2024
seems to be good ammo. I shoot 5.56 in my ruger 223. This box of 5.56 states, do NOT shoot in 223. So, I guess I will give to a friend since I don't own a 5.56 only. My mistake but just a heads up.
