The Griffin HEDP Barrels provide High Endurance Dual Purpose functionality- offering high durability and precision accuracy. Nitrided 416R stainless steel provides the highest possible hardness and longest throat life available with match grade bore dimensions and bore finish. HEDP barrel bores are hand lapped, ensuring batch to batch consistency and accuracy. TRUE-BORE concentric suppressor grade threads provide an optimized thread interface for your silencer regardless of brand or model. M4 feed ramps and chambers are polished prior to nitriding for smooth reliable feeding, chambering, and extraction. Gas ports were carefully engineered to provide reliable function suppressed or unsuppressed with 5.56 NATO ammunition. M4A1 contour diameter between the chamber and gas block for minimal POI shift with suppressors and maximum accuracy and durability while maintaining field weight.

5R rifling is believed by many to be superior to conventional rifling, reducing bullet deformation, and barrel fouling, affording more consistent accuracy, reduction of wear (greater life), and greater ease of cleaning.  5R rifling was used in the legendary Army M24 Sniper Weapon System (SWS) and those rifles were found to meet or exceed accuracy requirements at over 20,000 rounds fired.

The Gas Block (if added) can be pinned by a trained gunsmith. Alternatively end users can quickly mount their block with the included set screws. Proficient builders should use a carbide tipped 1/8in drill bit to complete the pin hole prior to pressing the gas block splined pin. (splined pin installation is optional)

NOTE: Gas Block is sold separately.
