Daniel Defense 10.3 CHF carbine length barrel shoots flat at SBR distances. Sub MOA with match ammo. Carbine gas at 10.3 is hot but cycles reliably. CHF process makes for consistent rifling. Quality DD barrel for SBRs.
DD 10.3 inch carbine length CHF barrel needed about 50 rounds of break-in before groups settled. Now consistent. Carbine gas at 10.3 is hot which is why this barrel exists, not for a casual build. Heat dissipates through the gas system fast.
