I bought a S&W M&P15 and later purchased some IMI M855

Customer Question

I bought a S&W M&P15 and later purchased some IMI M855 penetrator ammo .556/45 and I was thinking maybe I messed up! I'm not sure I can use them in a Remington barrel?

Thank you for using Just Answer!

My name is ***** ***** I'll be glad to help you.

M855 Penetrator (Green tip) is fine to shoot out of an S&W M&P 15, which is chambered for either 5.56mm or .223 Rem. calibers. It has an embedded lead core for more penetration, but other than that, it is a normal 5.56mm round.

I hope this helps.

I hope you understood that the rounds I purchased are Israeli military rounds under more pressure than basic m855 rounds. I appreciate your response, and hope you understood the ammo was IMI penetrator rounds! Thank you. Rob

Yes - that round's pressure is within specs for 5.56x45mm ammunition.
