This project gun build focuses on the PTR K3P, a 12-inch barreled G3K variant. Key modifications include upgrading the trigger pack housing and safety selector for better ergonomics, and installing an M-LOK rail. Critical technical adjustments involve replacing the stock 55-degree locking piece with a 50-degree one to prevent receiver damage, especially when suppressed, which can increase bolt velocity and cause 'roller dent'. Optic selection is also crucial, as wide optics can interfere with ejection.
This video details how to effectively suppress an H&K MP5-K PDW using the OSS RAD 9 suppressor. It highlights the advantages of the roller-delayed blowback system for suppression and provides specific technical modifications, including an 80-degree locking piece and the 'Gray' extractor spring, to optimize performance. The review also covers mounting options and ammunition choices for achieving optimal sound reduction and reliability.
