Buffbridge Custom in Thailand give their thoughts on the Tokyo Marui SAIGA-12K Gas Blowback Shotgun. The Tokyo Marui Saiga-12K is a faithful replica of the real-world Saiga 12K shotgun, which is known for its compact size. The "K" in the name stands for "Korotkaya," which means "short" in Russian. This gas-powered airsoft gun fires in semi-automatic mode, releasing three BBs with each trigger pull.
