Creating a free-floating handguard for an AR-10 rifle involves replacing the standard handguard with a free-floating model that does not contact the barrel. This enhances accuracy by eliminating the potential for the handguard to put pressure on the barrel and affect its harmonics.
Free-floating handguards offer several advantages, including improved accuracy, better heat dissipation, and the ability to mount accessories like bipods and vertical grips without affecting barrel harmonics. Historically, gunsmiths achieved free-floating handguards by extensive trial and error, but today, pre-manufactured free-float handguards are readily available.
