GNB (Gas Non-Blowback) refers to gas-powered airsoft guns that do not cycle the slide/bolt when firing. Compressed gas is used only to propel the BBs, not to move the slide as in GBB guns. This makes the mechanism simpler, quieter, and highly efficient in terms of gas consumption. Popular GNB models such as the Tokyo Marui MK23 and Novritsch SSX23 are commonly used as secondary sniper pistols or silent primary weapons for stealth engagements. You can find GNB guns in our online store.
