Barrel Lengths
This video explores the impact of barrel length on firearm performance, specifically for the AR-15 platform using 5.56mm/.223 caliber ammunition. It categorizes barrel lengths into short (10.5–12.5") for Close Quarters Battle (CQB) and home defense, mid-length (12.7–14.5") as a balanced compromise, and long (16–18"+) for maximizing long-range ballistics. The presenter emphasizes choosing barrel length based on intended mission rather than aesthetics and invites viewer participation through a poll on maneuverability vs. ballistics vs. balance.
