Better hope your computers and mobile gadgets can handle 4K as Airsoft GI goes full 4K video with this overview of the PTS Masada Gas Blowback Rifle... "After a long wait, the PTS Gas Blow Back Masada is HERE! Made by KWA, this rifle is compatible with standard LM4 magazines, and high gas efficiency that the LM4 line of rifles are known for. It comes with the new PTS Gas Blow Back EPM magazine which is both durable and good looking. This is great option for those who currently own an LM4, and want something to add to their arsenal that still can use the same magazines."
