SHOT SHOW 2020: CMMG New Products

This guide details the installation of the Magpul Enhanced AR Magazine Release, an upgrade designed to improve ergonomics for shooters with smaller hands or those seeking easier magazine manipulation. The process involves removing the stock release and installing the new component, which features an enlarged, serrated surface. The video also briefly covers the installation of an extended release option.

This video highlights the SpeedTac bolt carrier as a significant advancement for AR-15 platforms. The presenter explains its key feature: precision-engineered cutouts on the bottom that eliminate magazine tension during closed-bolt reloads, preventing rounds from being pushed down. This design aims to improve reliability, especially with fully loaded magazines, and is suggested to be a feature that should be standard on all AR-15s.

The Helix Gas Regulating System by Blackout Defense offers a tool-less, barrel-integrated adjustable gas system. It allows users to precisely tune gas flow from full closure to their preference, preventing bolt over-travel and enhancing reliability. A key design feature isolates critical components from carbon buildup, effectively eliminating carbon lock.

This guide, presented by an expert from GUNBROS, details how to add Quick Detach (QD) sling ports to an AR-15 platform rifle, specifically addressing the Ruger AR-556's lack of integrated options. It covers using M-LOK adapters, upgrading to stocks with built-in QD points, and modifying the end plate for single-point slings, emphasizing practical solutions for enhanced firearm maneuverability.

This guide details the installation of the Juggernaut Tactical featureless AR grip, designed to improve ergonomics and compliance in restricted states like California. The video highlights the grip's natural hand placement, a comfortable backplate, and an ambidextrous 45-degree safety selector. A live-fire demonstration confirms its secure feel and improved handling compared to traditional fin grips.

This guide, drawing from the expertise of AT3 Tactical, explains why standard carbine buffers might be insufficient for optimal AR-15 performance. It recommends exploring heavier buffers (H1, H2, H3) and advanced systems like the Odin Works Adjustable Buffer and Armaspec Stealth Recoil System to fine-tune recoil impulse and enhance the shooting experience by slowing the BCG.

This video hilariously tests a heavily accessorized AR-15, dubbed the 'Zombie Carbine,' as a parody of excessive tactical gear. The build, based on a Smith & Wesson M&P15, weighs 23 pounds fully loaded with 270 rounds across nine magazines. It features multiple optics, lasers, lights, and is demonstrated with rapid fire, hip sniping, and Tannerite explosions.

This "ultimate AR-15 meltdown" test pushes a custom build to its limits, revealing key durability insights. The Faxon barrel ultimately burst after 830 rounds, but critical components like the Sharps SRC bolt carrier group and Geissele rail demonstrated impressive resilience under extreme stress and heat. The test highlights the AR-15 platform's robust design, even when subjected to conditions far exceeding typical operational use.

This video showcases an extreme full-auto durability test of a premium Definitive Arms VEPR AK, comparing it to a budget WASR-10. The VEPR AK demonstrated exceptional resilience, enduring 895 rounds before failure, significantly outperforming the WASR-10 and even a previously tested AR-15. The expert analysis highlights the AK platform's inherent durability and heat management characteristics, even under severe stress.

This video demonstrates the legendary durability of the AK platform by subjecting a Yugo M92 PAP to a 700-round continuous firing test. Despite extreme heat causing significant smoke and glowing metal, the firearm remained functional, showcasing Mikhail Kalashnikov's robust engineering. The test concludes with a cooling process and a tribute to the designer's legacy.
