X-Ring offers a historical overview of the Sturmgewehr STG-44, the pioneering German assault rifle from World War II, detailing its historical context, design intricacies, and operational features, including magazine capacity, sighting systems, firing mechanisms, and performance at various ranges. An airsoft version of this rifle exists.

X-Ring reviews the real deal H&K PSG-1, which he says is the grail of semi-automatic sniper rifles. The PSG-1, a high-precision rifle developed by Heckler & Koch in response to the 1972 Munich Olympics massacre, has a storied reputation for reliability and performance. Designed to address the limitations of West German police units during the tragic event, the PSG-1 offers exceptional accuracy and a large magazine capacity.

X-Ring give their take on the B&T BWC9, a folding gun chassis design, at the range. The BWC9 is a folding chassis for SIG P320 pistols that unfolds from a compact, briefcase-like form into a rifle with a flick of the wrist.  It utilizes your existing P320 FCU and slide (subcompact to X-Five lengths) and includes an Aimpoint sight, but not suppressor-height sights.
