A quick look at this kit by Caffel of this 3D printed kit that is available on Cults3D. This system is designed to feed proprietary 3D-printed shells from a dedicated front-loading magazine. Concurrently, the standard AAP-01 magazine handles the supply of BBs and gas, ensuring the core firing mechanism remains intact.

Stupid Airsoft tries CO2 power chambers on the Action Army AAC-C1 to find out how much power it can produce. The initial green gas test showed weak performance, yielding low muzzle velocities of around 250 FPS and suffering from inconsistency due to gas cooldown. The experiment then shifted to the CO2 shells, which are color-coded (M130, M150, M170) and use smaller 8-gram cartridges to release escalating amounts of gas.

J. Kihope shows a third-generation KRISS Vector conversion kit designed for the Action Army AAP-01 airsoft pistol. The demonstration specifically focuses on the integration of the AAP-01 bolt into the Vector’s lower receiver, utilizing gas blowback magazines to achieve a realistic cycling action.

Stupid Airsoft checks the spring cylinder upgrade for the Action Army AAC-C1, a airsoft sniper rifle capable of running on gas, CO2, or spring power. He begins by detailing the internal components of the VSR-spec spring kit, highlighting the metal spring guide and a unique piston design that utilizes O-rings instead of a traditional piston cup. He notes that while O-rings may wear faster, they are significantly easier and cheaper to replace than proprietary piston cups found in other high-end models.

Stupid Airsoft does two external upgrades for the Action Army AAC-C1 airsoft sniper rifle: a quick pull bolt handle and a thickened butt plate. He first details the installation of the new quick pull bolt handle, which requires partially disassembling the bolt to attach the component and give the rifle a modern, speedsoft aesthetic.

Stupid Airsoft checks out the Action Army AAC-C1 gas airsoft sniper rifle, also known as the "Athena," which the he deems the most unique sniper on the market. According to him, its defining feature is its versatility, allowing it to run on either green gas or CO2, with the option to convert it into a traditional spring-powered rifle, all while retaining compatibility with VSR-10 upgrade parts.

Another AAP-01 feature by Stupid Airsoft showing how to install the Firewad Panther Carbine Kit Install designed for it. He focuses on installing and upgrading the upper receiver, detailing the process of attaching the new handguard, which is designed to integrate with the previously installed AK lower receiver.

Stupid Airsoft takes a good look at the Action Army Athena, also known as the AAC-C1, which he says is an innovative airsoft sniper rifle that stands out for its unique ability to operate using three power sources: gas, CO2, and spring. The rifle is noted for its compact, lightweight design, and it features an ambidextrous stock and a very smooth bolt pull. Its distinct gas system relies on a small, magnetic reservoir located inside the bolt assembly.

CaffeL demonstrates a 3D printed shell ejecting kit that converts the Action Army AAP-01 GBB pistol into an AK-style carbine. While its signature feature is shell ejection, the kit is designed to function as a regular carbine conversion even without the shells installed, making shell ejection an optional feature. For external attachments, the outer barrel is equipped with a 14mm CCW thread, allowing the use of various accessories via an adapter.

In this video, Stupid Airsoft checks out a custom lower for the Action Army AAP-01 made by King Slayer. He starts by detailing the King Slayer Grip, including its construction from ASA plastic with 100% infill, before demonstrating the installation of the hardware and fitment test. Key design features noticed are the trigger adjustment slot and the various grip panels and comfort options. He also examines the addition of a magwell flare and compares the assembly to the stock lower.
