This video features a range test and review of the RS9 Vampir, a 9mm DA/SA service pistol designed for Bosnian anti-terrorist police. The pistol, manufactured in the Republic of Srpska by TRB and imported by TCH Arms, is noted for its lineage to the Zastava CZ-99 but with modern updates like a shared decocker/slide-stop, polygonal rifling, and 18+1 capacity. The review highlights its similarity in feel to the SIG P226 and CZ REVOLVER 01, though it mentions a stronger single-action pull. Downsides include a high price point of $1,400, no optics-ready option, and a limited aftermarket.

This video reviews the Noveske Rival V2 AR-15 barrel, focusing on whether its premium price is justified. The review includes a detailed breakdown of specifications, a bore scope inspection, accuracy testing with multiple ammunition types at 100 yards, and velocity and stability analysis using specialized equipment. The presenter highlights unexpected build quality concerns, such as chamber finish and brass scarring, despite the barrel's excellent bore, rifling, and crown. The performance is compared against other SPR barrels, with results presented on a leaderboard. The video encourages viewer engagement and subscription for future in-depth reviews.

This video offers an in-depth analysis and accuracy test of the 16-inch Sons of Liberty Gun Works SPR Barrel. It covers the barrel's unique features like its .223 Wylde chamber, 1:7 twist rate, 3-groove polygonal rifling, and 5/8x24 threads. The review includes a borescope inspection of the internal quality, micrometer measurements of external dimensions, and a detailed shooting assessment with three 30-shot groups using different ammunition types (PMC Bronze 55gr, Hornady 73gr ELD Match, Berger 77gr OTM). The analysis focuses on mean radius, group size, velocity, standard deviation, and shooter-induced flyers. A new metric, A-ZED (A-Zone Equivalence Distance), is introduced to practically assess rifle performance at range. The video provides data-driven insights into the barrel's precision and performance.

This video focuses on the Danuvia VD-01, a relatively rare firearm, highlighting its unique features such as polygonal rifling and a helical barrel. While acknowledged for its historical significance in firearms development, the VD-01 is explored for its technical merits. The content is presented by Jonathan Ferguson, a firearms and weaponry expert, and is part of the "What is this Weapon?" series from the Royal Armouries, aiming to bring history to life through their collection.

This video explores the origins of the vz.82 pistol, a Western-style firearm developed for communist Czechoslovakia. Created by CZ to generate hard currency through exports, the pistol was a response to the obsolescence of existing service models. The project evolved to meet the needs of the Ministry of Defense for a 9x18mm Makarov pistol and the Ministry of the Interior for a police sidearm. The resulting compact pistol was produced in three calibers: .32 ACP, .380 ACP, and 9x18mm Makarov. The video examines an early prototype vz.82 featuring a decocking mechanism, along with a standard production model. It also highlights the use of polygonal rifling in the 9x18mm variants due to a then-cancelled cartridge with a sintered iron bullet, while the .32 and .380 caliber CZ 83 models utilized traditional rifling. Both vz.82 and CZ 83 pistols have seen significant importation into the US as surplus.

This TFBTV episode features James Reeves operating an RPG-7 Rocket Launcher Trainer. While the launcher itself is a destructive device, its fire control unit has been reactivated, and it fires a subcaliber unit housed within an inert rocket. This subcaliber unit fires 7.62x39mm rounds, with polygonal rifling and an over-bored design to simulate the trajectory of a real RPG-7 rocket-propelled grenade using tracer ammunition. The video also highlights various gear used by the hosts, including 5.11 Tactical apparel, Electric Knoxville sunglasses, Oakley M-Frames, Walker Razors ear protection, Surefire Sonic Defenders, and Garmin Fenix 6 watches.

This video features Keith Ford from Brownells Gun Tech examining the Czechoslovak CZ 82 pistol. He highlights its similarities and differences with the Russian Makarov, noting the CZ 82's chambering in 9x18mm Makarov, double-stack 12-round magazine, polygonal rifling, and ambidextrous controls. The video details its blowback operation, DA/SA trigger, fixed barrel, and unique disassembly via a swing-down triggerguard. It also touches on the CZ 82's military service in Czechoslovakia and its current status in Slovakia and the Czech Republic. The CZ 83, its commercial export variant, and its ATF "Curio and Relic" classification are also discussed.

This video reviews the F4 Defense PDW, a firearm that the presenter suggests could be the 'ultimate AR'.

This video explores a unique Glock barrel from IGB Austria that is reportedly unavailable for purchase in the US. The barrel features a hybrid rifling system, combining hexagonal and polygonal designs, and is constructed using a cold hammer forging process with a Plasmanitration coating. The creator highlights this as a "Match Grade Glock Barrel" and a "Glock Barrel Upgrade," specifically for a "Glock 19 Barrel," while acknowledging its rarity and difficultly to acquire.

This Glock torture test explores the reliability of a Glock pistol when fired with black powder. The video emphasizes safety warnings and highlights that this is an experiment by a "professional gunman" with experience in Glocks, reloading, and black powder. It tests the pistol's ability to fire a full magazine under extreme conditions with a very dirty powder. The description also mentions the surprisingly easy cleanup of the barrel with Ballistol and the potential for increased pressure with hardened black powder residue. Several supporting channels and sponsors are also listed.
