M&A Barrels are specified at 5.56 Nato, can I shoot .223 ammunition?

Not a problem. With our 5.56 chambering, you can shoot either with no issues. In a .223 chamber you are likely to have stoppages firing 5.56 ammo as the primers may blow out and foul in the lockwork mechanism of your lower. All of ours are chambered for 5.56, again- no problem!
