A quick overview on the gas blowback version of G&G's Combat Machine by Operador 'Airsoft' BR which he owns for some time now. G&G’s Combat Machine line, a popular budget-friendly AEG line, has introduced the M4 Raider GBBR Airsoft Gun. This model retains the beloved Combat Machine platform but incorporates a closed-bolt gas blowback system. It boasts high-quality polymer receivers, an adjustable LE stock, a removable rear sight, and front and rear sling points. The M4 Raider GBBR Airsoft Gun offers an affordable entry into the world of GBBR airsoft guns, making it an excellent addition to any arsenal. Its lightweight polymer design, characteristic of the CM16 GBB, reduces field fatigue, allowing for extended play.
