Whether you're new to the sport or an experienced skirmisher seeking a sidearm with performance as a priority, the Action Army AAP-01 Assassin GBB Pistol is exactly what you need! Boasting a super speedy design, a massive aftermarket of customisation options and impressive performance straight out of the box, the AAP-01 changed the game when it first dropped and continues to dominate CQB sites across the country, especially when fitted with an HPA adapter! 
Starting at the front end we can find a knurled thread protector concealing 14mm CCW male barrel threads beneath. This is a fantastic feature for an out-of-the-box pistol, especially at this price; allowing you to install the most common tracer units and suppressors easily with no need for additional adapters. An AAP with a tracer is a match made in heaven, we recommend the EShooter Flare M if you're taking your AAP into CQB!
The outer barrel itself is a fluted design, intended to mimic real steel target shooting pistols which use fluting to save weight and encourage the dissipation of heat built up in the barrel. The fluting is a big contributor to the AAP's unique looks, giving it a sleek style with hints of the Ruger Mark IV, one of the most well-respected target shooting pistols in the real steel world. 
On top, we can find the iron sights which are a fantastic set of high-vis light enhancing sights with an orange insert in the front sight and green inserts in the rear. This ensures you don't mix up the sight dots and pull shots off when shooting under pressure and also enhances target acquisition speed and low-light visibility.
