Jaeger Precision talks about the Maruyama SCW-9 SD2 Pro Gas Blowback Rifle (GBBR), also known as the APC9 Pro, and its compatibility with a shared magazine system across other Maruyama SMGs. He first unboxes the SD2 model, which features an enlarged M-Lock handguard and an included suppressor extension, noting the benefit of the magazine platform for airsofters who own multiple compatible replicas.

A main segment demonstrates the rifle's modularity, specifically showing how the suppressor extension can be easily installed and contains an adapter for hiding a tracer unit. He likes the SCW-9’s design, noting the fully ambidextrous controls (mag release, fire selectors, and charging handles) and a very responsive trigger pull.

During a performance test, the rifle was initially found to be shooting low power, which was quickly identified as a restrictive screw for UK importing purposes. He demonstrates the simple fix of removing the screw to restore the expected 1 Joule output.
