Amped PreBuilt HPA Gearbox | Drop-In HPA V2 Gearbox
Installing an HPA unit into your pre-existing AEG can be challenging. Our solution? The Amped Airsoft Prebuilt HPA Gearbox! Our HPA Gearbox allows you to install an HPA unit into your favorite V2 compatible Airsoft Rifle without the need to modify your existing gearbox. Our Pre-Built HPA Gearbox comes with your choice of HPA unit, gearbox color, IGL and trigger.
These gearboxes are compatible with most VFC / Tokyo Marui Compatible lower receivers on the market.
For stocks that attach via the nut and spring guide, you have a couple options:Option 1: Take your existing spring guide and cut it down to make room for the solenoids and wiring depending on your HPA unit. Typically this can be easily done with a Dremel or saw. Option 2: Take your stock screw to the hardware store and purchase a nut and washer to allow you to attach it to your lower receiver.Option 3: Purchase the Wolverine Buffer Tube Adapter we have listed in the product options above. This will work the same way as Option 2.

Lightweight and highly durable construction
Made from 7075 T6 aluminum alloy, the same material used in aerospace with a maximum tensile strength of 570MPa.
Instead of the standard alloy threads, stainless steel inserts are used in the gearbox to prevent aluminum thread twisting, and steel washers can be replaced at any time.
To achieve perfect side-to-side gearbox alignment in the receiver, two front screws can be used.
The gearbox is coated with a special anode and available in four colors: Gold, Blue, Black, Red, and raw aluminum, appealing to those who appreciate the look of CNC machined aluminum.

“Once upon a time, in the mystical land of Amped Airsoft, I embarked on a perilous quest to transform my humble EMG M16A1 into a weapon worthy of the gods. It was not a simple task, for the ancient tomes of airsoft lore spoke of the HPA gearbox—a marvel of engineering that few dared to craft and even fewer could perfect. I ventured to the wizards of Amped Airsoft, who dwell in a fabled workshop said to rival the forges of Hephaestus himself. With trembling hands, I sent forth my weapon, entrusting it to their legendary artisans. Days passed like eternity, and I awaited their word with bated breath, like a hero awaiting the prophecy of their destiny. When the day finally came, and the Redline N7 Milsim gearbox was delivered to my hands, I was awestruck. Amped Airsoft had not merely created a gearbox; they had imbued it with the very essence of rad power. This was no ordinary custom HPA gearbox—nay, it was a masterpiece forged by airsoft demigods. The trigger response? Lightning fast, as if Zeus himself powered each shot. The consistency? Unwavering, like the resolve of a noble knight. The craftsmanship? Immaculate, a testament to their tireless dedication and otherworldly skill. The packaging? Not even the most disgruntled USPS worker could have marred its contents. But what truly sets Amped Airsoft apart is their commitment to their craft. Throughout the process, their sages kept me informed, sharing updates and offering wisdom on trigger selection and compatibility. They treated my humble M16A1 as if it were Excalibur, ensuring every detail was perfect. Now, on the airsoft battlefield, I pose to be unstoppable. My foes will tremble in there out box, before the might of the Amped-forged HPA powered M16A1, and I stride forth as a hero reborn. If you seek greatness for your airsoft armory, look no further than Amped Airsoft. They are not mere merchants—they are the legendary smiths of our age, and their work is nothing short of magic. Five stars? Nay, five kingdoms’ worth of stars for Amped Airsoft! Long may they reign as the masters of the craft.”

“Converted my ARP9 to HPA using the drop in P* Jack gear box set. Everyone was super helpful and talked me through everything I would need. Converted the lower to a CM16 I bought from a boneyard and was able to get all the parts needed to get it up and running. The drop in kit was simple, quick, and extremely easy!!”

“This was my intro to HPA and it couldn’t have been simpler. Amped built it to specs and I dropped it in my replica. Amped does a great job of putting everything together so you don’t have to.”
