Please turn on the subtitles. I show you my KJW / Haw San Mad Max Shotgun (wa shan double barrel) with a Madbull Conversion Kit. With this kit you can use now the Madbull Shells for the Tanaka M870. The original Shell are leaking and have no performance. This Kit is selfmade (gunsmith) and not to order. Now the Shotgun rocks like a shotgun :-) ► YOU LIKE ? - CLICK 2 SUBSCRIBE: ◄ ------------------------------------------------------------------------------------------------ Full Review (Chapter) 0:25 Datasheet 0:35 KJW vs. Madbull Shell 1:50 The Conversion Kit 2:46 Installation 4:53 Chrono 5:26 Target 6:00 Shooting 7:30 Closeup ----------------------------------------------------------------------------------------------- Product Brand: KJW / Hwasan Hop-Up: No Weight: 1560g Length: 470 mm Capacity: 2 x 6 rds Power: 550 fps Power Source: Gas Blowback: No Shoo
