Description
Product Details

The Ultimate Transformation (Speedsoft & HPA):
Tired of running out of gas or BBs at the climax of the action? Are you a pure assault player who wants a devastating rate of fire? The CTM TAC M4XIMUS kit revolutionizes your Action Army AAP-01. This Lower Frame pairs perfectly with any Upper (original or custom like the FUKU-2) and allows you to power the pistol with classic M4 AEG rifle magazines. You'll have the handling of a pistol combined with the firepower and autonomy of an assault rifle!

Extreme Construction and CNC Trigger:
Designed to withstand abuse on CQB fields, the receiver is molded in reinforced nylon with a staggering 45% fiberglass. Despite its robustness, it keeps the weight down to just 310 grams. The design integrates side windows to control the flow of BBs and a brilliant BB-Lock system that prevents BBs from falling out when you remove the magazine. In addition, the kit includes the new CNC aluminum VELO-M4XIMUS Trigger as standard, micrometrically adjustable for pure competition sensitivity.

Main Advantages

M4 AEG Power: Forget gas magazines. Use your high-capacity or low-cap M4 magazines with ultra-high capacity.
BB-Lock System: Zero wasted BBs. Clean and fast magazine changes without the classic rain of BBs on the ground.
45% Nylon Fiber: Unrivaled impact resistance, designed to support heavy magazines without flexing.
Match Grade Trigger: Integrated adjustable VELO trigger for lightning-fast shots (Note: this kit does not support triggers from other brands).

Components NOT Included (to be recovered from the original pistol)

Upper lock button and spring
Trigger lever and spring
Original magazine release button and spring
Gas Route Bucking (Nozzle seal)

Pro Maintenance Tips for Assembly and Use

PAY ATTENTION TO PRESSURES (HPA): The adapter and valve are designed to operate with pressures between 80 and 120 PSI. Pushing the regulator above 140 PSI will not give you magical advantages, but will cause catastrophic failure of the pistol's mechanics and damage to the adapter. Stay in the recommended range for perfect bursts and total reliability!

The Importance of M4 Magazines: The kit theoretically mounts any airsoft M4 magazine, but in HPA systems with a very high Rate of Fire (ROF), the magazine spring must be very powerful to push the BBs fast enough not to "skip" shots. We strongly recommend using the legendary PTS EPM or EPM-1 mid-caps. They are an investment, but they will solve any feeding problems.

Prepare the Tools (DIY): Buying this kit means wanting to get your hands dirty. You will have to completely disassemble the trigger group (the hammer cage) of your old AAP-01 receiver and transplant it into this new M4XIMUS. Equip yourself with punches of various diameters, Allen keys, a rubber mallet and a lot of patience. If you don't feel safe, rely on the experience of our M Tactical Custom Lab for a state-of-the-art assembly!
