The 
Tokyo Marui Recoil DEVGRU TM416D Custom
 is a high-end, full-metal electric blowback (EBB) airsoft rifle in their Next Generation Recoil Shock (NGRS) system, renowned for its realism, durability, and accuracy. It is based on a customized Heckler & Koch HK416D used by the U.S. Navy SEAL Team Six
 
Key Features
Recoil Shock System: This rifle features Tokyo Marui's proprietary NGRS Version 2 gearbox, which provides a satisfying and powerful simulated recoil and bolt movement with every shot, enhancing realism during gameplay.
Stop-on-Empty Feature: When used with the proprietary NGRS magazines, the rifle stops firing once the last BB is fired. The user must insert a new magazine and press the bolt catch to resume shooting, mimicking the action of a real firearm.
High-Quality Construction: The receiver, outer barrel, buffer tube, and handguard are constructed from durable metal, giving the airsoft gun significant heft and a realistic feel. The barrel assembly is free-floating for better stability.
Accessories Included: The DEVGRU custom version typically comes with a Quick Detach (QD) silencer, a vertical foregrip, and flip-up front and rear sights.
Magazine Options: It includes an 82-round steel housing magazine that can be switched to a more realistic 30-round capacity mode for Mil-Sim games. High-capacity 520-round magazines are also available for purchase.
Performance: Tokyo Marui AEGs are known for their exceptional stock range and accuracy, even at lower muzzle velocities (around 300-320 FPS for UK models).
Ambidextrous Controls: The fire selector switch is ambidextrous, and the trigger guard is removable.
