M4 AR15 MK18, metal, Alpha, ETU, black, Delta Armory, A07-ETU

M4 AR15 MK18, metal, Alpha, ETU, black, Delta Armory, A07-ETU. Automatic electric airsoft gun (AEG). Replica model M4 AR15 MK18 [DA-A07-ETU] in black design by Delta Armory. Airsoft guns of the Alpha series are characterized primarily by a full metal design, higher quality internal parts, a D5 QD pistol grip and a straight CNC type-A trigger. Another interesting feature is the QRS (Quick Release System) of the second generation, which enables quick replacement of the spring and motor without disassembling the body. Each piece is equipped with a unique serial number. The designation ETU (Electronic Trigger Unit) indicates that the weapon is equipped with a modern processor unit with the possibility of user settings. It therefore completely replaces outdated switching contacts. The ETU in combination with the assembly of internal parts and recommended battery, offers a short reset of the trigger and a quick shot after pressing it.

Modern type M4 with metal RIS handguard MK18, which allows the use of other tactical accessories. The tactical retractable stock (6 adjustment positions) has a rubber boot and a place to store the battery in the bumper tube.
