G&G GR4 G26 BLOWBACK AEG ASSAULT RIFLE BLACK, made from metal (including steel) and polymer. Steel elements include the shell ejection window cover, forward assist, trigger and flash hider as well as iron sights. Stock slide, internal barrel and the majority of small elements were made from a uniform zinc and aluminium alloy. The stock pad, handguard and receiver of the replica were made from polymer. The stock’s length is adjustable, which allows adapting the replica to the changing conditions and body type of the user.
The fire mode selector is located on the left side of the receiver and is marked with graphical descriptions of fire modes. The replicas feature a PBB system, which imitates very well the operation of the live firearm equivalent. It sets the bolt carrier dummy into motion and provides a noticeable “kick” of the replica into the user’s arm.
