This non-blowback ARM is an offical licensed product. We build the AEG as close as the real steel, the appearance and markings are flawless. The specs are identical to the real firearm so most of the accessories for the Galil are compatible with our AEG (e.g. handguard, stock and scope mount). In order to create more realistic shooting experience, the special designed bolt carrier operating mechanism was installed to simulate the real firearm blowback action. One of the best features of this AEG is the Betalight Ready Tritium night sight set. And a dummy selector is installed on left side of AEG to stick with the original design. Even it is an AEG, it is still a very robust piece because it is build with Nylon Fiber handguard, 6065 Aluminum receiver, and steel top cover and parts.Package comes with a BB loader and a 130 rounds magazine.
