This video provides an expert evaluation of the Zastava ZPAP M90 as a suppressor host. The instructor, demonstrating significant experience with AK platforms, highlights the ZPAP M90's adjustable gas tube as a key advantage. Contrary to common expectations for AKs, the suppressed ZPAP M90 is found to be surprisingly low-gassy, making it one of the least gassy AKs the instructor has tested with a suppressor.

This video provides an expert overview of Primary Weapons Systems' (PWS) new Mk2 Mod2 large frame rifle and BDE modular suppressors, presented at SHOT Show 2026. The Mk2 Mod2 features a long-stroke piston system, ambidextrous controls, and bore evacuator technology for reduced gas blowback. The BDE suppressors are highlighted as 3D printed titanium, modular, and hub-compatible units. The presentation emphasizes technical details and design innovations.

This review details the practical accuracy of the Palmetto State Armory (PSA) JAKL in 5.56x45mm NATO, tested up to 600 yards. The rifle demonstrated high consistency in a practical accuracy course, hitting steel targets from 150 to 500 yards with impressive reliability. Extended testing at 600 yards confirmed its capability as a mid-range precision tool, despite minor ergonomic and recoil observations. The JAKL offers a significant performance-to-price ratio when compared to more expensive platforms like the FN SCAR.

This comprehensive review of the Beretta AR-70/223, famously known as Big Boss's rifle in Metal Gear Solid V, delves into its Cold War development. The AR-70 aimed to blend AK reliability with NATO ergonomics and the 5.56 cartridge. Expert analysis covers its design philosophy, practical manipulation, and detailed field stripping, highlighting its unique piston-mounted recoil spring and AK-derived bolt.

The Kel-Tec PLR-16 is reviewed as a lightweight, affordable 5.56 NATO pistol option, often overlooked as a truck or backpack gun. While praised for its compact design and AK-like piston system, its polymer construction and trigger are noted as potential drawbacks. The firearm is highly customizable with standard AR accessories and aftermarket braces.

This video provides an expert overview of the Kel-Tec PLR-16, highlighting its innovative design for its time. The speaker, demonstrating high authority, details its long-stroke piston system, polymer frame, AR-15 magazine compatibility, and features like a folding brace and threaded barrel. The PLR-16 is presented as a precursor to modern AR pistols, showcasing forward-thinking design elements.

This video provides a first look at the WBP AK-AR prototype, a 5.56x45mm rifle merging AK reliability with AR-15 magazine compatibility. Key features include a bolt-on AR magwell, right-side bolt release, ambidextrous mag release, and standard AK furniture compatibility. The rifle retains the long-stroke piston system and features a 1:8 twist fluted barrel with M14x1 LH threading and a PSO optics rail. Development is ongoing with a focus on reliability testing.

This video reviews the Primary Weapon Systems (PWS) MK116 Mod2, an AR-15 rifle featuring a long-stroke piston system. The review highlights the rifle's AK-47-like reliability combined with AR-15 accuracy and modularity. It explores the PWS AR-15's performance in real-world use, comparing it to other rifles in its class, and details its build quality, recoil management, reliability, and unique features, positioning it as a potential AK-47/AR-15 hybrid. The content aims to inform both experienced AR owners and newcomers about PWS's innovative piston AR-15 design.

This video offers a detailed explanation and comparison between the AK-47 platform and the PWS Mark 111 rifle, specifically focusing on the long-stroke piston operating system. It delves into the mechanical differences and potential performance implications of these two distinct rifle designs. The description also promotes the creator's other YouTube channels and social media platforms.

This video compares the three main AR-15 operating systems: Direct Impingement (DI), Short Stroke Piston, and Long Stroke Piston. DI is simple but dirtier, while piston systems keep the action cleaner but add complexity. Long stroke pistons offer AK-like reliability but can increase recoil, and DI systems may offer better accuracy due to fewer moving parts.

This video showcases a meticulous build of the PWS MK114 rifle, featuring an ASMR-style assembly process. Key components include the PWS MK114 upper and lower receivers, a PWS BDE titanium suppressor, and a dual-optic setup with an EoTech Vudu 3-9x24 LPVO and an EoTech EFLX red dot. The build emphasizes precision with the use of a Wheeler FAT Wrench for torquing and a PWS FRC compensator.

This video showcases the JAKL-10 Rifle, specifically highlighting its 16-inch variant. The description details its construction around a monolithic 6061 rifle-length upper receiver, designed for compatibility with the PSA PA-10 Gen 3 lower receiver. Key features include an in-upper buffer system for reduced length, a long-stroke piston system, a dual ejector bolt, and an AK/AR hybrid carrier. The JAKL-10 also boasts an ambidextrous, toolless side charging handle and an 8-position toolless gas block for easy adjustment. The firearm is designed for toolless field stripping and cleaning.
