An 18″ heavy barrel is a thick-profile barrel designed for AR-15 or AR-10 rifles, providing enhanced accuracy, reduced barrel flex, and better heat management during sustained fire. It works with compatible upper receivers, rifle or mid length gas systems, gas blocks, gas tubes, handguards, bolt carrier groups, and lower receivers. The 18″ heavy barrel is ideal for precision shooting, competition, and long range builds, offering reliable cycling and consistent performance for demanding applications.
