Hako got the new Tokyo Marui Glock 17 Gen 5 MOS GBB pistol and takes it to CQB Delta if it is good as a primary in tight spaces... "Hello, this is Hako! I tried using Tokyo Marui's new Glock17 Gen5 for a survival game out of the box! This product has been highly rated for its ability to operate even in cold winter environments, and I think this is truly an excellent product. Please watch until the end!"
