Double Eagle M813 M4 Sportline AEG with M203 Grenade Launcher
Get ready to dominate the battlefield with the Double Eagle M813 “Grenadier” – a versatile and feature-packed airsoft rifle that brings twice the firepower in a single platform. This full-size M4 RIS AEG combines the reliable electric performance of an M4A1 with a spring-powered, tri-shot M203-style underbarrel shotgun. Whether you're sweeping corridors in CQB or laying down suppressive fire in the field, the M813 has you covered from all angles.
Firing in both semi and full-auto modes, the M4 delivers up to 250-300 FPS with adjustable hop-up for increased accuracy. Mounted beneath is the M203 tri-shot grenade launcher that fires three BBs per trigger pull using airsoft shotgun shells—perfect for clearing tight spaces or ambushing opponents. With a retractable LE-style stock, integrated 20mm RIS system, and removable carry handle with a railed top receiver, this rifle offers excellent adaptability for custom loadouts. The included battery and charger make this a ready-to-go setup for beginners or anyone looking to add some fun firepower to their arsenal.
