What does it mean; “fires from most AR-15’s?” Currently have a 5.56 / .223 AR-15; does this statement suggest ammo might not / will not work in my rifle?
Answer:
Hi JDM! That sentence only acknowledges that many AR-15s are chambered for other cartridges (e.g. 6.5 Grendel, 6.8 SPC, 350 Legend, etc.). So long as an AR-15 is chambered for 5.56x45 (like the vast majority are), then it should have zero problems firing M855.
