    There is a mental and physical checklist that shooters should run through before running their rifle suppressed. First off, do you have a suppressor? Great, one major hurdle down. Next in line should be preparing your host weapon for its new role as a silenced blaster. Concentric muzzle threading and for the Ar15 platform, proper gas mitigation is at the top of the list. Supppressor manufacturer Griffin Armament has solved these issues and more with the release of their HEDP suppressor-ready barrels.

    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.
