For short-barreled 5.56 AR-15s, the speaker recommends M855A1 service ammunition or a 62-grain bonded soft-point bullet (like the FBI load) for optimized expansion. For 300 Blackout, the 110-grain Barnes Triple Shock is highly regarded.

What are the advantages of a 10.3-inch barrel AR-15 like the Daniel Defense Mark 18?

A 10.3-inch barrel AR-15, such as the Daniel Defense Mark 18, is ideal for its light weight, handiness, and ease of carrying. It excels in close-quarters combat, general patrol, and home defense scenarios.
