If you are in the process of adding some custom flair to your AAP-01, this part may be of interest to you! Introducing the Action Army Thumb Stopper for the AAP-01 Assassin GBB pistol, a "Gas Pedal" style thumb stop constructed from aluminium using CNC processes. This part is intended to provide additional recoil control and encourage a consistent grip by giving your thumb a place to rest, and letting you apply downforce to the muzzle to keep those full auto bursts under control!

Full description


The AAP-01 Thumb Stopper is precisely CNC machined from aluminium and is available in either matt black, metallic red or silver, meaning no matter what your build objective, the Thumb Stopper will fit right in! The Thumb Stopper can be installed on either the left or the right side of the AAP-01, allowing it to be used by both left and right handed shooters with equal functionality.

The piece attaches to the pistol via an attachment plate, which is installed on the front receiver screw and the lower receiver's trigger pin, covering the manual safety but providing a super stable mounting point for the Thumb Stopper. If you are a speedy type of player, we are sure you never use the manual safety anyway, as it is far quicker to rely solely on the EU style two stage trigger to provide the safety necessary to minimise the chances of a negligent discharge. 

The Thumb stopper can be installed over the top of its attachment plate in two different positions, allowing you to choose the most comfortable angle for you and your hand size. This part is inspired by real steel "gas pedal" style thumb stops, intended to provide a place for you to rest your thumb and apply additional downforce to keep the muzzle rise of both pistols and rifles under control. 

If you are leaning into the AAP-01's advantages with your build, and seek an increase in handling speed, recoil control and grip consistency, the "Gas Pedal" Thumb Stopper from Action Army will be a perfect fit!
