Palmetto State Armory announces the PSA Sabre Mixtape Black Album, a new variant of their popular AR-15 platform. This release caters to customer demand for a blacked-out version, featuring enhanced ambidextrous controls, a specific trigger, and a dedicated 300 Blackout suppressor. The video details key components and provides a launch date and time.

The Witt Machine Canooter Valve is a monocore suppressor primarily designed for .223 caliber firearms but also compatible with .22 caliber. It claims to achieve 136 decibels at the ear with a 16-inch AR-15. While not intended to be 'dead quiet,' it effectively directs sound forward. The suppressor is noted as being slightly heavier but durable and functional for both .223 and .22 calibers.

This video compares the 6MM ARC and 6MM MAX cartridges, highlighting their technical differences, performance, and practical applications. While the 6MM ARC has gained significant traction and military adoption, the 6MM MAX offers potential advantages in AR-15 compatibility due to its use of a standard 5.56 bolt. However, the performance differences are noted as minuscule in real-world scenarios, with availability and existing adoption favoring the 6MM ARC.

This video explores the effectiveness and drawbacks of suppressing auto rifles, specifically AR-15 platforms, by testing accuracy, back pressure, heat mitigation, flash signature, and sound suppression. It highlights how suppressors can impact accuracy due to increased heat and mirage, increase back pressure leading to fouling and potential health concerns, and significantly alter thermal and IR signatures. The analysis suggests that while suppressors offer benefits like flash reduction, their use on auto rifles requires careful consideration of the specific suppressor technology and operational context.

This review of the Ridgeback Rhodie 6 suppressor highlights its hybrid diameter design, forward venting system, and Inconel construction. Instructor Aaron C. of Sage Dynamics found it to be exceptionally reliable across various platforms, including short-barreled rifles and full-auto configurations. The suppressor demonstrated excellent performance in managing gas, reducing recoil pulse, and maintaining a low muzzle signature, even under night vision conditions.

This video showcases the IWI ARAD 5, an AR-15 style rifle featuring a piston-driven system. The presenter highlights its compatibility with standard AR-15 lowers, allowing for extensive customization. The build process involves upgrading various components, including the magwell, trigger, muzzle device for suppressor use, charging handle, and safety selector, transforming it into a more complete and personalized firearm.

This video showcases a novel magnetic optic mount for pistols, demonstrating its quick attachment and detachment capabilities. The speaker tests its retention by racking the slide, highlighting its potential as a firearm innovation. While initially shown on a Glock, the mount is available for other platforms like Sig Sauer and HK.

This guide covers the basic operation and features of the EOTECH OGL, a compact laser aiming device. It highlights the interface controls, including the activation button and the illuminator adjustment lever, and explains the benefit of co-aligned visible and IR lasers for simplified zeroing. The use of VCSEL technology is also noted.

This entry details the innovative Full Conceal M1 system for the Sig P320 and a prototype Folding Glock 19, both designed for enhanced concealability. The M1 system, priced at $899, integrates an 18+1 capacity with a smartphone-like footprint and active retention. The Folding Glock 19 prototype showcases a unique mechanism for rapid deployment from a compact state, utilizing a 23-round 9mm magazine. Expert insights from Chris Tran (Guns & Tactics Magazine) and Mike (Full Conceal) highlight the technical aspects and practical applications of these designs.

This guide, drawing on expert instruction from UN12 Magazine, details the critical steps for properly installing and maintaining firearm sights. It emphasizes the use of witness marks on red dot sights to ensure screw security and highlights the importance of checking iron sights for mechanical integrity to prevent zero loss. Proper installation and regular checks are vital for all sighting systems.
