The PBG Customs HK Army Stainless Steel Regulator Bonnet Upgrade is a precision-machined replacement bonnet designed for compatible HK Army Standard, AeroLite, and HP8 tank regulators.
Its stainless-steel construction provides a more durable threaded connection between the tank regulator and marker ASA. The upgrade is designed to help reduce thread wear, galling, and the possibility of the bonnet seizing in an ASA after repeated installation and removal.
The PBG Customs design also features high-volume airflow and dual O-rings and is precision CNC machined in the USA.
