Stupid Airsoft shows how to the Jefe Airsoft Smooth Pull Trigger bar V2 into an AAP-01 airsoft pistol. He also compares the Jefe Airsoft trigger bar, an aluminum, skeletonized design, to both the stock and CTM steel trigger bars, pointing out its unique features like a larger, more aggressive activator and concave areas to reduce friction.
Stupid Airsoft does an installation of Jeff's Airsoft stainless steel extended bolt release on a DMR AAP-01. The extended bolt release offers improved actuation, especially with a carbine kit, and features a sandpaper-like texture for enhanced grip. Made from a durable material, it is less prone to bending or rusting than stock versions. The installation process involves disassembling parts of the AAP-01, including the hammer and trigger bar, and carefully reinstalling springs and pins.
