Russia's pump-action grenade launcher: the GM-94. With firearms and weapon expert Jonathan Ferguson

This YouTube video, titled "Lança-granadas vs Pistola Sinalizadora: Qual é mais insano?" (Grenade Launcher vs. Signal Pistol: Which is more insane?), directly compares two distinct types of projectile-launching devices. While the exact models and calibers are not specified in the provided data, the title strongly suggests a comparative analysis of their capabilities and 'insanity' factor. This implies a focus on performance, visual spectacle, or perhaps tactical applications. The content likely explores the differences in power, range, and potentially historical or modern uses of a grenade launcher versus a signal pistol.

The AN-94 'Abakan' is a rare Russian assault rifle designed by Gennadiy Nikonov, featuring a unique 'hyperburst' mode capable of firing two rounds at 1800 RPM. Its complex internal mechanism includes a reciprocating barrel and a pulley system, distinguishing it significantly from the AK-74. The rifle also accommodates specialized accessories like the 6X5 bayonet and GP-25 grenade launcher.

This Albanian ASh-78 variant from 1982 showcases unique modifications for rifle grenade launching, including a relocated rear sight on a stabilized top cover and a gas cut-off mechanism.

The full-length barrel under the spigot suggests improved ballistics for standard ammunition.

This review of the Kel-Tec KSG bullpup shotgun addresses the common concern of heavy triggers. While initially feeling 'horrible' during dry fire, the trigger significantly improves during live fire, offering a noticeable reset. The reviewer also highlights the surprisingly smooth pump action, a positive attribute for this platform.

This review covers the Mossberg 590RM Chisel, a magazine-fed, 12-gauge pump-action shotgun with an 11-inch barrel, classifying it as an SBS. The design incorporates AR-style controls and a detachable box magazine, a significant upgrade for capacity in short-barreled shotguns. The presentation is informative, highlighting key features and technical specifications.

Palmetto State Armory is developing the PSA 570, a highly modular 12-gauge shotgun platform. The design emphasizes user-buildability, allowing customization of barrel and magazine tube lengths. Future compatibility for semi-automatic configurations is planned, and it will accept Remington 870 furniture, offering extensive aftermarket support. Endurance testing is nearing completion, with an official announcement anticipated soon.

This video features Ian McCollum and Jonathan Ferguson in a 60-second challenge at the Royal Armouries to find three unique firearms: a Charlton Automatic Rifle, a Schwarzlose Model 1898 pistol, and an early SA80 prototype.
