Yes, 5.56mm ammo can be safely fired in an AR-15 model SP1, as the SP1 is designed to handle both .223 Remington and 5.56mm NATO cartridges. However, it's essential to ensure that the specific barrel and chamber are compatible with 5.56mm ammunition. Since the SP1 is an older model, it's a good idea to verify its condition and consult the manufacturer or a knowledgeable gunsmith if unsure. Always prioritize safety and follow proper guidelines when handling firearms and ammunition.
