KJ Works Full Metal M4 RIS Airsoft GBB Gas Blowback Rifle

FPS Range: 450-480

Scope not included
KJW joined up with Tanio Koba to bring us their latest revision to their M4 Gas Blowback Rifle project. Running on its own proprietary gas system, the KJW GBB M4 RIS is remarkably efficient. The blowback system generates a healthy amount of recoil, giving it a very realistic feel. The rifle comes standard with a blank receiver which is perfect for custom engraving any logo or insignia you may want. Externally it’s built solidly and when matched with the steel reinforced internals it provides a great out-of-the-box gun. The M4 RIS comes standard with front and rear flip-up sights, a RIS front end, and rail panel covers to match.

Features:

• Hard-kick blowback system
• Heavyweight, metal alloy construction
• RIS front end for tactical accessories
• 3x polymer rail panel covers included
• Railed upper receiver
• Aluminum outer barrel
• Flip-up front and rear sights
• Matte black finish
• Steel and metal alloy internal parts provide great reliability
• Heavyweight magazine
