About Tapp Airsoft

In 2014 we released our first product, the famous Tapp Triggers which gives players the ability to shoot semi-auto consistently and quickly, giving players a huge competitive advantage. The Tapp Trigger was the first and still is the only paintball-style trigger in the airsoft community. We followed up that innovation with the Tappazine. The Tappazine integrates perfectly with gas blowback and HPA systems to provide players with a non-stop supply of high-pressure air. With the Tappazine it's possible to maintain an amazing FPS rate all day long without ever needing to refill gas canisters. The Tappazine was great, but we wanted to do more, so in 2017 we designed and produced the Tapp Drum. With a 1500-round storage capacity, the Tapp Drum completely eliminates the need to reload. Getting rid of those few seconds it takes to switch mags gave us a crazy advantage-not to mention, we never had to worry about running out of ammo again. At the same time as we were developing our own products, our team grew from 2 to over a dozen players and we started sponsoring other teams and players as well. Today TAPP Airsoft is both a team and a company, proud to bring the latest in competition products and gear to the Airsoft community.

"I bought one for my KWA mp9. Works beautifully. Feeds perfectly. Haven't had any issues with the mag itself. My only issue i have right now it that the gun tends to dry out quickly from using air instead of the silicone in green gas. I'd recommend over lubing your gun or putting a few drops in the gas chamber of the mag before connecting the air line.

Would also recommend the short mag for the mp9. The full size mag with the drum attached to the bottom is kind of unwieldy. Short mag is perfect.

"Just took this drum magazine out for a joy ride with my Mp7 in CQB games and man oh man. This is the best investment Ive ever mad other than the power up surpessor I just bought for it. My Mp7 was enjoyable with my tapped mags at about 40 rounds in each mag but id fire off about 5 rounds before I knew where my BB’s where traveling. This drum mag enables me to just run and gun and pelt areas waiting for an enemy to walk in my stream of endless fire. My Mp7 has never been funner to play with and with an HPA attachment I wont ever have to worry about green gas refilling and reloading is out of the picture. The feature with the pull cord is super easy to grab and pull to reset the sping tension on your BB’s. All in all this has made my Mp7 such a fun gun to play with and Im looking forward to ordering more of these for my other guns.

"I have ordered multiple drum mags for various guns from TAPP directly and Evike.

Two of the G&P WOC M4 mags I ordered from Evike both leaked on arrival. To fix them I disassembled them and added fresh teflon tape to parts where the segments of the magazine combined. The way they implemented the drum mag to the m4 mag could use some work. The drum portion is so far from the rifle that it looks bad. A whole portion of the m4 mag is essentially useless and the whole product would have been better if they could have just used the top portion of the m4 magazine and attached the drum portion to the bottom.

One Hi-Capa mag from TAPP worked perfectly on arrival, another one I ordered from TAPP had a slight leak and tightening the screw to the 3D printed part fixed it. The HPA valve is pretty close to the handle so enhanced magwell flares would have to be removed for the magazine to go in properly.

Finally a short Vector mag I ordered from TAPP worked perfectly on arrival, no complaints. The only issue is the HPA valve sits right underneath the bottom plate where I liked to put my support hand.
