Abstract: A regulated gas block assembly may include a gas block including a barrel receiving bore, a gas tube receiving bore, and an intermediate passage extending from the barrel receiving bore to the gas tube receiving bore. The intermediate passage may be oriented at an oblique angle with respect to the barrel receiving bore. The intermediate passage may include a gas regulator seat, and a gas regulator may be positioned and removably secured in the gas regulator seat. A barrel including a gas ring recess may be fit to the regulated gas block assembly.

Abstract: A firearm sound suppressor and associated methods. The suppressor can include first and second firearm connectors at opposite ends of the suppressor for connecting to firearm mounts of different types. The suppressor can include symmetrical baffling and/or symmetrical gas flow passaging such that sound reduction performance of the suppressor is generally the same notwithstanding whether the first or second firearm connectors is used to connect the suppressor to the firearm. A protector can be used to protect the firearm connector that is not connected to the firearm.
