CMMG Q&A Rides Again! Radial Delayed Blowback

This guide from 704 Tactical provides essential knowledge for suppressing AR-15 platforms. It details various suppressor types, including direct thread, hub mount, and low back pressure options, and explains how to diagnose and tune an AR-15's gas system for reliable suppressed operation. Key tuning methods involve adjusting buffer weights, recoil springs, and utilizing specialized BCGs and charging handles to mitigate excess gas.

This video details the final stages of an AR-9 SD (suppressed/deactivated) build, focusing on the installation of a Midwest Industries handguard designed to tuck a suppressor. The build features a Noveske barrel and a CMMG 36K suppressor, resulting in a remarkably quiet and reliable firearm. The presenter also highlights the upgrade from an A2 grip to a Dier Co pistol grip for improved ergonomics.

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 guide details how to troubleshoot and tune an AR-15 equipped with a Forced Reset Trigger (FRT) that experiences a 'one click' failure. Expert instructor Brody from Juicey Media explains the importance of BCG velocity and dwell time, demonstrating how buffer weights, springs, and buffer systems like the VLTOR A5 can resolve cycling issues, especially when using suppressors. The video emphasizes that each rifle requires individual tuning to find its optimal 'sweet spot' for reliable FRT operation.

During ammo shortages, the next items to disappear are magazines, reloading components, and gun parts. The video highlights that during the 2020 shortage, specific magazines like Glock and AR-15 Pmags became scarce and expensive. Reloading primers vanished almost overnight, while powders remained available but restricted. Gun parts for popular platforms like AR-15s (lower parts kits, BCGs) and Glocks also saw significant demand and scarcity, impacting repairs and builds.

This video from CF Clips discusses a potential issue with the SIG Sauer MPX firearm and its compatibility with FRT (Forced Reset Trigger) triggers. The core problem identified is the MPX's heavy bolt, which can reportedly damage or break FRT triggers due to the force of the bolt carrier group impacting the hammer. This insight comes from direct communication with FRT manufacturers, who have confirmed the MPX's harshness on their triggers.

This video demonstrates the correct 'rock and lock' technique for inserting AK-47 pattern magazines into the CMMG Mk47 rifle. It highlights a common user error of 'mag-locking' by attempting AR-15 style straight insertion, which leads to malfunctions. The instruction emphasizes that mastering this AK manual of arms is crucial for reliable operation of the Mk47 platform.

This guide details the installation and function of the CMMG P3 (Personal Position Preset) Screw System. The P3 screw, found in the Zeroed grip's storage compartment, installs into the Fastback receiver extension. It allows users to set a predetermined stop position for adjustable stocks or braces like the RipStock and RipBrace, enhancing consistent shouldering. The guide includes specific tool requirements and adjustment methods for both the RipStock and RipBrace.

This guide details the installation and basic usage of essential AR-15 accessories, including slings, charging handles, handstops, triggers, flashlights, and optics, as presented by Mike from CMMG. It emphasizes proper fitment and function checks, while reinforcing that proper training is the most critical element for any firearm owner.

This guide details the installation of the CMMG .22LR Conversion Kit into a standard AR-15 platform. The process involves removing the existing bolt carrier group and inserting the conversion unit. The video emphasizes the cost-effectiveness of .22LR ammunition for training and introduces new shooters to the AR platform with reduced recoil. It also highlights compatibility nuances, particularly for Mk57 platforms.
