Description
Product Details

Unibody Construction (The Art of CNC):
Tired of the original plastic lower of your AAP-01 flexing under stress? CTM TAC has invested months of research and development to create the ExoFrame. There are no joints or weak points: this Lower is literally sculpted from a single, solid block of 6061 aircraft aluminum using high-precision CNC machinery. The "exoskeleton" (Skeleton) design is not only an aesthetic masterpiece, but guarantees absolute stability to the internal firing group, eliminating flex and making the trigger even crisper and more responsive.

Advanced Ergonomics and Perfect Balance:
Despite being a metal monoblock, the clever weight-reducing cuts stop the scales at just 134 grams. This extra weight compared to plastic, positioned right in the grip area, lowers the pistol's center of gravity, perfectly balancing the weight of the Upper (especially if you use suppressors or tracers), reducing muzzle flip during rapid fire in Speedsoft. In addition, CTM TAC has included a very convenient oversized button for releasing the Upper in the design, to facilitate and speed up field disassembly.

Main Advantages

Extreme Rigidity (Unibody): Single-block aluminum construction without joints for maximum resistance to abuse on the field.
Optimized Balance: 134 grams concentrated in the grip for superior recoil control.
Quick Disassembly: Oversized CNC aluminum Upper release button already included.
Exoskeleton Design: Aggressive and unique look, perfectly combinable with CTM Uppers (FUKU-2, Reaper, CMU) and miniskirts (Magwell).

Pro Maintenance Tips for Installation

HEART TRANSPLANT (Trust M Tactical!): Please remember that this is an external upgrade. The box contains only the fantastic empty aluminum shell. To make it operational, you need to disassemble the original lower piece by piece and transfer the entire firing group (trigger, safety, springs, hammer, magazine release, and pins) inside the ExoFrame. It is an extremely delicate operation: if you do not have great manual skills with GBB mechanics, no problem! The specialized M Tactical workshop is at your disposal. Contact us to entrust the work to our technicians and receive your customized AAP-01 expertly crafted and ready to fire!

Optimal Lubrication: Having moved the mechanics from a plastic shell to a CNC metal one with very tight tolerances, the friction changes. If you do the work yourself, before closing everything, put a dab of lithium grease or thick silicone oil on the pins and friction points of the hammer and trigger. The trigger will become smooth as oil and very fluid.

Complete the Work: A Lower like this deserves a matching miniskirt (Magwell). By adding a CTM TAC Magwell to the base of the grip, you will not only speed up magazine changes incredibly, but you will perfectly close the design of the exoskeleton, transforming the AAP-01 into an absolute racing jewel.
