TaktOpAirsoft shows how he assembled a custom gas blowback rifle after receiving a Noveske Chainsaw receiver kit. To complete the build, various internal and external components are sourced from existing airsoft guns, including a G&P MWS and a Guns Modify 416. This process involves selecting parts such as the buffer tube, grip, and bolt to create a functional firearm from a bare frame.

The build encounters several mechanical challenges during the troubleshooting phase. An initial two-stage trigger fails to perform correctly, and the bolt frequently jams in the rear position within the buffer tube. By identifying issues with part compatibility and spring tension, he replaces the problematic components with a Guns Modify trigger box and a different buffer spring to ensure smooth operation.

He then concludes with a live-fire testing session at an outdoor range in which he demonstrates the rifle’s reliability through various shooting drills and transitions, focusing on the speed and accuracy of the completed project. After verifying that the mechanical issues are resolved, he expresses satisfaction with the final performance of the custom-built rifle.
