With a length of 78.0 cm, this model falls into the all-round size category: comfortable to handle at both indoor and outdoor locations. The weight is 2.8 kg, which you will certainly notice after a longer skirmish day; a sling is a smart addition in that case. The stock is adjustable, allowing you to quickly fit the replica to your own build or kit. Thanks to the extensive Picatinny rails around the handguard, the model is easy to equip with optics, grips, lights, or other accessories. As an AEG, you need not worry about gas or temperature: it runs on a battery, making this a hassle-free choice for long skirmish days. Important note: always disconnect the battery after play and use a charger with a storage mode to keep your LiPo in good condition.
