About this pistol barrel
Diamondback 300P85H50B8R DB Barrel 300 Blackout 8.50" Pistol-Length Black Nitride 4150 Chrome Moly Vanadium is a pistol barrel for AR-15, 8.50 in, 1:8 in twist.
Match the pistol model, generation and slide length exactly; a barrel one generation off will not lock up correctly. Drop-in barrels fit most factory slides, while match-grade barrels may need a gunsmith to fit the hood and lug.
