Viper Tech M16A4. Comes with 1 GHK G5 mag, 2 GHK Stanags, 1 EB Tech mag, and a G&P Pmag. None leak. Rifle functions fine, and everything is in good condition. Will trade possibly for other high end GBBR packages, HPA packages, or a decent PTW build. Viper Tech are the best and bar none the most realistic GBBR's on the market. 6061T6 forged aluminum receivers, CNC machined and oil hardened steel trigger group/barrel/bolt, 7075T6 billet aluminum nozzle. They are built identically to a Colt rifle, using old Colt machines. If you have any questions feel free to message me. Thanks :) Note: I also do custom work and build HPA/GBB/AEG setups. Message me if you need work done 👌
