Review on 🔒 O-Ring Paintball Air Tank Fill Nipple - Captain Edition [Includes Bonus CO Microfiber Cloth] by Kevin Singleton

After getting frustrated with the Japanese-named "N” mini-fill valve I ordered earlier (because it leaked badly), I was a bit reluctant to get this valve from Captain O-Ring to order. But much to my delight, this air tank filler nipple works great! Installed it as a volumetric fill valve on my Beeman Qb78 Deluxe. I modified the original barrel cap so I can now use CO2 or HPA to charge my airgun.
