The FB Radom Grot is slated for US import in Summer 2024, with pistol and rifle variants approved. This 922r compliant firearm features ambidextrous controls, a short-stroke gas system, and AR-15 magazine compatibility. Pricing is estimated around $2,499 for the pistol and $2,700-$2,800 for the rifle, positioning it as a premium alternative to established platforms.

This review of the Stenzel SAK-21 highlights its unique indirect gas-operated system, which combines elements of short-stroke and tappet systems, drawing comparisons to the SCAR and VZ 58. The firearm features a tunable gas block, an integrated bolt hold-open, and a two-stage trigger, differentiating it significantly from traditional AK platforms. The reviewer emphasizes its modularity and potential for caliber swaps, positioning it as a modern, heavily engineered defense weapon.

This video reviews the Reap Industries SAI, an innovative bullpup conversion for AR-15 platforms. The SAI allows users to transform their existing AR-15 lower receiver and upper into a more compact bullpup configuration without requiring an FFL transfer for the SAI unit itself. The reviewer highlights its lightweight design, modularity, and how it maintains many AR platform benefits while offering a significantly different form factor. Installation and potential trigger feel adjustments are discussed, along with the inspiration drawn from Eugene Stoner's BRN180 upper.

This review of the B&T APC Pro series, specifically the APC 308 Pro and APC 223, highlights their premium build quality and smooth operation, comparing them to the SCAR and traditional AR platforms. The presenter emphasizes the rifles' exceptional recoil mitigation due to features like a hydraulic buffer and short-stroke gas system, making them incredibly soft-shooting. While expensive, the B&T APC Pro series is presented as a top-tier option for those seeking a refined and high-performance rifle out-of-the-box.

This review details a mud test performed on a Bushmaster ACR, a firearm originally designed by Magpul and later manufactured by Remington and Bushmaster. The test involved multiple submersion cycles in mud, followed by firing sequences to assess reliability. Despite some noted issues like magazine retention failure and a failure to lock open on the last round, the ACR was deemed to have passed the mud test, with the speaker attributing some failures to mud ingress during magazine changes and calling the firearm rare.

This short review highlights the CZ Bren 2 MS as a compelling alternative to traditional AK platforms for shooters who prefer the 7.62x39mm cartridge. Key advantages discussed include its 5/8x24 threaded muzzle for easy accessory attachment, an ambidextrous side-charging handle, improved backup sights, and a full-length Weaver rail for optics. The reviewer also notes the potential for reduced recoil due to its short-stroke gas system.

This video compares the AR-180 and the Sig Spear LT, highlighting their shared lineage from Eugene Stoner's designs. While both utilize a short-stroke gas piston system and rotating bolt, they differ significantly in construction materials and modern features. The AR-180, a civilian variant of the AR-18, features stamped sheet metal construction for cost-effectiveness, while the Spear LT uses machined aluminum for a more robust and modular platform. The comparison emphasizes the evolution of firearm design from the AR-180's foundational concepts to the Spear LT's contemporary ergonomics and accessory integration.

This video provides a detailed comparison between the FN SCAR 16S and the CZ Bren 2, focusing on their design, features, and internal components. The presenter highlights differences in materials, ergonomics, and disassembly procedures, ultimately concluding that the CZ Bren 2 offers a more refined and durable package despite similarities in their AR-18 based operating systems. Both rifles are noted for their accuracy and reliability, but the Bren 2 is favored for its better lower receiver, trigger, and stock durability.

This video provides a concise overview of the Canadian WS-MCR, often referred to as Canada's AR-180B. It highlights key features such as its 5.56 caliber, 18.6-inch heavy barrel with a 1:8 twist, free-floated M-LOK handguard, and a short-stroke gas system. The presenter notes its mil-spec trigger, last-round bolt hold-open, AR-style controls, and its non-restricted status in Canada, making it a modular and affordable option.

This video provides a comprehensive overview of the VZ 58 rifle, often referred to as a 'non-AK' due to its distinct internal mechanisms despite some aesthetic similarities to the AK platform. The presenter details its history, production, and technical specifications, highlighting its short-stroke gas system, falling breech block action, and unique linear hammer firing system. It also covers variations, magazine differences, and aftermarket support.
