Okisaba checks the performance of the Salvo Precision MCX RATTLER, a gas blowback airsoft rifle based on the Tokyo Marui MWS system. He praises its high quality, metal construction, and detailed SIG markings, calling it a great value for around 65,000 yen. Its compact size and ambidextrous controls make it highly maneuverable.

He then proceeds to customizing the rifle, including adapting a SIG 7.62 suppressor and setting it up with a compact red dot sight. The rifle's performance in a firing test is strong, showing good accuracy thanks to the MWS internals, even though the short-stroke system results in a lighter recoil.

Finally, he tests an aftermarket Falcon P-Mag, which proves to be more reliable for gas capacity than the original magazine. Overall, he gives a strong endorsement of the MCX RATTLER as an accurate and high-quality airsoft option.
