CTM TAC CNC UnderMount Picatinny Stock Adapter for AAP-01 / AAP-01C (SPEED Magwell Compatible)

Rock-Solid Stock Mounting. CNC Aircraft Aluminium. Purpose-Built for Speedsoft Dominance.

Transform your sidearm into an ultra-compact carbine setup with the CTM TAC CNC UnderMount Picatinny Stock Adapter for AAP-01 / AAP-01C. Custom-engineered by CTM TAC for speedsoft players, CQB operators, and custom GBB builders, this dedicated lower stock adapter installs directly onto the base of your grip to give you a rigid 1913 Picatinny rail interface for mounting folding stocks, brace adapters, or sling mounts.

Precision CNC-machined from 6061-T6 aircraft-grade aluminium, this adapter is purpose-built to integrate seamlessly with the CTM TAC CNC SPEED Magwell for AAP-01 / AAP-01C. By positioning the stock interface lower on the frame, it maintains clean sightlines for mounted red dot optics while providing a rock-solid, wobble-free anchor point for rapid shoulder-transitions and superior recoil control during high-tempo skirmishes.

Key Features

• Dedicated SPEED Magwell Fitment: Purpose-built exclusively to lock into the CTM TAC CNC SPEED Magwell for AAP-01 / AAP-01C, providing an ultra-secure, integrated fit with zero movement.

• Standard 1913 Picatinny Rail Interface: Features a rear-facing Picatinny rail section for mounting 20mm/M1913 folding stocks, buffer tube adapters, or QD sling plates.

Tech Tip for Your AAP-01 Stock Adapter

• Magwell Compatibility Warning: This model is designed exclusively for the CTM TAC CNC SPEED Magwell and will not fit standard grip bases or other CTM magwell variants without the SPEED magwell installed.

• Threadlock Critical Hardware: Gas blowback vibrations and stock torque can loosen mounting screws over time. Apply a small drop of medium-strength blue threadlocker to the mounting bolts during setup.

• Pairing Stock Systems: Pair this undermount adapter with CTM TAC's TwinFold RIS Rail Stock or compact 1913 folding stock adapters for a lightweight, ultra-packable CQB primary build.
