The B&T TP9, an evolution of the Steyr TMP, is a compact PDW with a unique rotating barrel system. While offering extreme compactness for roles like vehicle work, it suffers from significant gas blowback, especially when suppressed, and a poor trigger. Its ergonomics are heavily right-hand biased, and iron sights are inadequate, necessitating an optic. Reliability issues with carbon buildup during suppressed full-auto fire require frequent maintenance.

This guide details the expert-level process for adjusting the FAL gas system, as demonstrated by InRangeTV. Proper adjustment is crucial for reliability, especially when using surplus ammunition or preparing for competitive shooting. The procedure involves incrementally increasing gas pressure until the bolt reliably locks open on an empty magazine, then adding a margin of error for real-world conditions. This technique ensures optimal cycling performance for the FAL rifle.
