This video explains the concept of free-floating barrels in AR-15 platforms, highlighting how they improve accuracy by preventing handguard contact with the barrel. Unlike traditional AR-15s where handguard pressure can shift the point of impact, free-float barrels attach solely to the receiver, preserving barrel harmonics. This design is crucial for precision shooting and custom builds.
