The Mayo Gang MGC4 Airsoft Gun is coming back stronger than ever!


We at Airsoft GI, in collaboration with the airsoft gun manufacturer Lancer Tactical, have developed a new airsoft rifle to meet the demands of the ever expanding Mayo Gang; The MGC4 AEG!

We are bringing back the Mayo Gang MGC4 Airsoft Gun by popular demand! However, we listed to all of you and what you wanted to improve. The Original MGC4 Airsoft Gun will now include an upgraded 25K High Torque Motor for increased rate of fire! Don't you worry, this upgrade will keep the amazing trigger response that we aimed for in the original limited set! For everyone who missed out on the first batch, you now have a second chance at owning airsoft history!

This Airsoft GI rifle is a true exclusive and as such, we wanted the absolute best, which is why it was built using the beloved internals of the Gen 3 lineup from Lancer, meaning you'll get the same quality components including the Nebula mosfet! The motor however has been swapped for a much more powerful high torque motor, giving the shooter a much more responsive trigger response and a faster rate of fire. The gears are also an upgraded set, allowing the airsoft rifle to withstand longer play with almost no friction. In addition, this airsoft gun sports an all new exclusive metal receiver specifically developed for this collaborative project only! Now you can proudly rep the Mayo Gang flag wherever you play!

Do not miss out on this limited edition airsoft rifle, once the word gets out, it'll be gone before you know it!

Cisco's Notes:

We wanted to bring an airsoft gun that represented the #mayogang in the best way possible and the MGC4 was created! After doing a lot of research, we chose the Lancer Tactical Gen 3 as the base platform. They offer an amazing internal build out of the box! Inside the Gearbox you get a 18:1 CNC Wire Cut Gear Set, Full Metal Rack Piston, 8mm High Speed Bearings, Metal Quick Change Spring Guide with Ball Bearings, 25k High Torque Motor, and the Zion Arms Nebula Programmable MOSFET! To finish off the internals, you are getting a 6.03mm Tight Bore Inner Barrel and Rotary Hop Up Unit. We thought about how we can take the MGC4 to the next level and we added the Full Metal Receiver to increase durability. For the rail, we couldn’t settle for anything for any plain jane mayo. For this we has added the sleek M-LOK Rail to keep the weight down and keep the capability of adding as many accessories you want. The Slim SOPMOD Stock and Enhanced Pistol Grip finish the furniture and provide comfort and ergonomics. Over all I am personally very happy with the MGC4 and you will be too!
