Mecânica 6mm takes a good look at the Silverback Airsoft MDR-X AEG, including the internals. This product is made under an exclusive license from Desert Tech LLC and features fully engraved markings with a unique serial number. The receiver, outer barrel, and muzzle brake are made of 6000 series aluminum, while the stock, grip, and handguard are constructed of PA6 Nylon reinforced with fiberglass and a synthetic rubber buttpad. The MLOK handguard has 3 slots at the 3, 6, and 9 o’clock positions, and there are 2 steel QD attachments at the rear of the stock. The fire selector and magazine release are ambidextrous with 3 points, and the ejection panels can be swapped for realism. The cocking lever is also ambidextrous and moves realistically.
