Simo GBB's last review for 2024 is the SIG MCX Gas Blowback version made by Toxicant Airsoft... "This time, we will be shooting an MCX made of ultra-premium gas brotoxicant, which is fitting for the last one! It seems to be quite difficult to obtain, but a friend of SIMO bought it from someone who had previously lent it to me for a video at a very low price! So, it's the same unit, but I filmed it again lol I gave up on filming the inside this time because there was a risk of losing parts, etc. (^^; I included a little bit in the previous video, so please take a look at that. This time, the temperature was 7℃ at the end of December, so the magazine was slightly warmed up before firing. The previous owner may have tinkered with it, but it worked well and the trajectory was quite good for a gas blowback ☆ The recoil is quite light, so I don't recommend it for people who care about recoil lol It's also great that you can use the magazines of the Oi M4! If you already have an Oi, you don't need to collect magazines. If I have the chance, I'd like to film it again in the warmer months."
