A player under our own install video asked: "So when the m4 mag runs out you basically lose 30 rounds as they don't get fed into the hi capa? They just sit in the pistol mag?" Fair question. When the M4 mag runs dry, a stack of BBs is still parked inside the pistol mag body. You don't lose them. They wait for the next mag. What happens to the BBs when the M4 mag runs dry? Our install tutorial shows how the adapter works. You pull the spring and follower out of your Hi-Capa mag, slide the feed tube...

The field filled you to 3,000, and twenty minutes later the gauge reads a few hundred less. An r/paintball player asked why their 48/3000 tank "loses pressure right after airing up." Short answer: an HPA tank hot fill heats the air, and the reading drops as it cools. Usually nothing is broken. Why does an HPA tank hot fill read low later? Fast fills heat the air and the bottle. Hot air pushes harder, so the gauge reads high at the station, then settles as the tank cools. The New Jersey Scuba air fills page says the proper way to...

You sold your old bottle online and now you have to get it to the buyer. An r/paintball player asked how to pack and ship it after doing the same. Short answer: you can't just drop a charged bottle in a box, and before you ship an HPA tank you need to empty it and check the carrier's rules first. Can you ship an HPA tank by mail? Not charged, and the empty case is murky. Compressed air fits USPS Publication 52's Division 2.2 definition for nonflammable gases. It bars any container whose internal pressure tops 180 psig at 130°F,...

The tank holds air fine until you fill it, or it hisses from the fill port while you're gearing up. An r/airsoft player posted "HK Tank Fill Nipple Leaking?" with that problem. Short answer: an HPA fill nipple leak is usually a worn poppet o-ring or a thread seal, and both are cheap fixes. Why is my HPA fill nipple leaking? The fill nipple is a quick-disconnect male fitting with a small poppet inside that lets air in and keeps it there. ZDSPB's tank tech page calls these low maintenance parts that may need an occasional o-ring swap when they...

Your pistol still cycles, but the needle is hugging the bottom of the dial. An r/airsoft player asked "When HPA tank is completely empty?" and the honest answer is that your HPA tank gauge and your gun will tell you different things. The gun usually quits being useful well before the needle hits zero. How do you read an HPA tank gauge near empty? The tank gauge shows bottle pressure, not what reaches the gun. Player report: replies in that thread said the tank is empty when the gauge sits at zero and no air comes out when you connect...
