RAP4 is proud to introduce the MKV Internal Air-Through Upgrade Kit, the exclusive way to get rid of steel braided hoses and bottomline ASAs on a wide range of popular markers! Upgrade your Tacamo MKV, Tippmann 98, US Army Carver 1, Operation Salvo, Alpha Black, or BT-4 marker…by routing your air directly through the rear of the receiver!
The MKV Internal Air-Through Upgrade Kit replaces the receiver's end cap with one that provides a threaded ASA, allowing you to attach any size of CO2 or HPA tank directly to the receiver. Even better - this allows you to attach a host of air-through stocks that give you remote line attachment points, conceal onboard air sources, fold to the side, and more! Best of all - once you install the MKV Internal Air-Through Upgrade Kit on your marker, you can take your steel braided hose and bottomline ASA right off and forget about them, because now you can achieve the maximum level of realism afforded by running your air directly into the receiver!
The MKV Internal Air-Through Upgrade Kit comes with all of the parts needed to install a hidden air line inside your marker that connects from the receiver's end cap to your power tube. This kit includes a new power tube, a specially designed connecting rod and power tube air valve, a tombstone cover to keep dirt out of the former air inlet, the air line pipe, and that threaded receiver end cap. With just a screwdriver and a few minutes of your time, you'll be able to swap in these custom internal parts, reassemble your marker, and get right onto the field to try it out!
Improve the balance of your marker when you couple the MKV Internal Air-Through Upgrade Kit with the RAP4 stock of your choice. Improve your marker's look and attain the ultimate in realism when you upgrade with the MKV Internal Air-Through Upgrade Kit. Then dominate your opponents with the truly custom, high-tech MKV marker you equipped with the latest in air-through technology! When you're serious about paintball, you seriously need to get an MKV Internal Air-Through Upgrade Kit for your Tacamo MKV, Tippmann 98, US Army Carver 1, Project Salvo, Alpha Black, or BT-4 marker!
