Axem Gas Tube Kit Carbine Roll Pin SS is a spare part for the AR-15 platform, which includes a gas tube sized for a carbine-length gas system and a roll pin. The package is designed to ensure reliable gas transfer and operational reliability in the AR-15 system, and its stainless steel construction makes it a durable maintenance and assembly component.
The gas tube is made of stainless steel, which withstands heat and corrosion over time. The tube's bends and port locations adhere to AR-15 standard dimensions, supporting consistent pressure management and cycling during firing. The included roll pin facilitates installation and securely locks the tube to the gas block reliably.
Carbine sizing means the tube's total length is typically about 24.8 cm (9.75 in), and the outer diameter is about 4.6 mm (0.180 in), fitting standard AR-15 gas blocks. The roll pin dimensions are typically about 2.0 mm x 12.7 mm (0.078 in x 0.5 in), ensuring it fits the gas block ear tightly and securely. Stainless steel withstands heat cycles and combustion gas impurities, supporting a long service life.
Compatibility covers standard-dimension AR-15 uppers and carbine-length gas blocks (e.g., low-profile or FSB-style), provided a carbine gas system port is present on the barrel. Installation is achievable with conventional gunsmith tools, and the roll pin installation locks the tube to the gas block without additional adapters. The carefully finished stainless surface supports easy cleaning and reduces fouling.
