Umarex N2 Regulator Adapter Features The Umarex USA N2 Regulator Adapter threads directly onto a NitroAir N2 cartridge giving Gauntlet and similar air rifle owners a way to power their rifle without a traditional hand pump. The M16x1.5 threading on the nitrogen end mates securely to the cartridge while the 5/8-18 threading on the regulator end connects to the rifle s existing regulator setup. That dual thread design lets the adapter bridge the two components cleanly without needing extra hardware. For hunters and shooters who want a lightweight way to top off air pressure in the field this adapter removes the bulk of carrying a pump altogether. Finished in black and weighing just 0.20 pounds the adapter is compact enough to toss in a pack or a range bag as a backup option. It is especially useful on small game hunts where carrying a full size pump is impractical or unwanted. Because it is compatible specifically with NitroAir N2 Cartridges and the Gauntlet2 air rifle shooters can count on a dependable fit rather than guessing at compatibility. This adapter gives Umarex air rifle owners a simple reliable way to keep shooting without missing a beat in the field.
