The Umarex N2 Regulator Adapter provides a quick and efficient backup air source solution for PCP airgun users. Designed to work with the Umarex NitroAir system, this adapter allows shooters to bypass compressors or pumps by threading a NitroAir cartridge directly onto compatible air rifles such as the Gauntlet. Ideal for small game hunts or unexpected compressor failures, the N2 Adapter keeps you shooting when traditional air sources aren’t available. It features M16x1.5 threads on the nitrogen side and 5/8-18 threads on the regulator side, ensuring a secure and reliable fit.
