Hardened Arms 5.56mm Integral suppressor is purpose built with entry teams in mind. Developed to retain the best ballistic performance of the 5.56mm cartridge, while keeping the firearm length as short as possible. Measuring out at an overall barrel length of only 12.9 inches, this is the ideal setup for a Short Barrel Rifle or an AR Pistol. The user serviceable monocore design allows you to avoid carbon build up, and a 17-4 stainless suppressor means years of durability and sound suppression.

Note: The barrel length of this upper requires a Pistol Lower or a SBR registered lower per ATF requirements. You are responsible for complying with state and federal law.
