Introducing the Mayo Gang MGC4 MK4 Full Metal M4 AEG with ETU Airsoft Rifle

The highly anticipated Mayo Gang MGC4 MK4 is here! Building on the overwhelming demand from the #mayogang community and the success of previous models, Lancer Tactical has once again partnered with Airsoft GI to bring a fresh evolution of the fan-favorite series. The MK4 combines the proven billet receiver and Nebula II ETU with new upgrades for even more precision, performance, and flair.

Next-Level Design and Functionality

The new 10.5-inch M-LOK handguard and included metal mock suppressor give the MGC4 MK4 a refined, aggressive look that’s ready for any loadout. The addition of a Top Down Center (TDC) hop-up chamber allows for more precise tuning of your shots, ensuring consistent accuracy shot after shot. Combined with ambidextrous controls and a comfortable new NSR stock, this rifle delivers the perfect balance of style and practicality.

Performance Upgrades that Deliver

Inside, the MGC4 MK4 continues the legacy of high-end performance. Featuring 16:1 steel gear sets, a 25k high-torque NEO motor, and low-resistance wiring, this rifle provides superior trigger response and fast cycling. The Nebula II MOSFET offers programmable functionality, while the Quick Change spring system makes FPS adjustments simple and field-ready.

MILSIM Ready

The Mayo Gang MGC4 MK4 AEG is a great pick for the MILSIM community largely because its handguard is as versatile as it is tactical—featuring seven M-LOK mounting sides toward the front so you can run lights, grips, or other mission-critical gear exactly where you want. It also includes two QD sling attachment points (one on each side of the rail), giving you flexible sling options for fast transitions and modular load-outs. The choice to revert to a forged-style receiver set rather than a more stylized Billet aesthetic really helps it blend into the realistic aesthetic many MILSIM players demand. All in all, this AEG balances practical accessory capability with a look and feel that fits straight into a serious, realism-driven scenario.

The Ultimate Rifle for the #MayoGang

The MGC4 MK4 is not just an airsoft gun — it’s a community icon reborn. Whether you’re running it on outdoor fields or dominating CQB matches, this rifle gives you the performance edge and unique look that defines the Mayo Gang legacy. Don’t miss your chance to own this limited collaboration that blends innovation, reliability, and style.
