Stupid Airsoft unboxes the KWA TAC-9 gas blowback rifle, marking his initial collaboration with the manufacturer. He explicitly notes that this session is a first look rather than a final, deep-dive evaluation. The packaging suspends the replica between two pieces of foam, a design choice that catches his attention as an unusual break from standard foam trays.

Examining the exterior, he points out the combination of a polymer receiver and an aluminum upper section. He tests the folding stock, finding it sturdy, and samples the ambidextrous fire selector and magazine release. A standard orange muzzle tip is promptly evicted with an Allen key because he finds it painful to look at, though he appreciates that it was merely held by a grub screw instead of being permanently pinned.

The presentation moves to mechanical testing, where he checks magazine compatibility with existing MP9 hardware. He engages in a minor wrestling match with an automated speedloader that tries to chew up the magazine feed lips, prompting him to quickly abandon the tool. A few test shots reveal a smooth bolt travel cycle supported by dual recoil rods and a trigger that clicks cleanly during its reset.

By the end of this video, the TAC-9 undergoes a quick chronograph test using propane gas to measure velocity. Stupid Airsoft discovers a user-friendly hop-up system that adjusts with a clicky dial using a bare finger rather than requiring a proprietary tool.
