In this video from CTM Tac, the first step focuses on the trigger pin installation, where the main advice is to put down the heavy tools. Treating the pin like a stubborn nail with a punch tool can actually deform the feeding tunnel, leading to permanent feeding headaches. Instead, a soft mallet and a gentle touch will keep the components aligned without turning your expensive kit into a paperweight.

Watch Stupid Airsoft use the Tapp Airsoft HPA shotgun shell adapter for the UMAREX/VFC UMP45 airsoft rifle.

Connecting the adapter to an HPA (High-Pressure Air) tank also eliminates the green gas cooldown issue, ensuring more consistent performance, especially in cold weather.
