This video provides a quick tip for owners of the CMMG Mk47, demonstrating a simple technique for achieving reliable magazine drops. The presenter explains that by holding the firearm at a slight downward angle (around 30 degrees) and actuating the magazine release paddle, the magazine should detach easily. The description also includes links to CMMG's website and social media channels for further engagement.

Paul Harrell, a recognized authority in the tactical YouTube community, delivers a challenging message about firearms readiness. He emphasizes that most individuals do not train sufficiently, particularly in varied scenarios like off-hand shooting or under high stress. Harrell also stresses the importance of stockpiling common ammunition calibers and warns against overconfidence and preparing for unrealistic self-defense situations.

This video from CMMG explains the technical differences between their patented radial delayed blowback operating system and traditional straight blowback systems. It details how radial delay uses bolt rotation to slow cycling, reducing felt recoil and wear, while traditional blowback relies on heavy components. The instructor highlights key component differences in bolts and upper receivers, emphasizing the tunability of the radial delayed system for various ammunition and suppressed use.

This video explains the phenomenon of light primer strikes in AR-style firearms, attributing them to the design of the floating firing pin. The instructor demonstrates how a floating firing pin can leave a small dimple on the primer even without a full ignition, which is normal for many AR-15 and AR-10 platforms. It also touches on how some blowback AR systems mitigate this effect.

While CMMG does not officially recommend a break-in period for their firearms, this instructor personally believes in one for metal-on-metal components like the bolt carrier group and chamber adapter lugs. He suggests that shooting the firearm allows these parts to conform to each other, potentially improving reliability. He emphasizes the importance of familiarizing oneself with any new firearm and testing it before relying on it for self-defense.

This video demonstrates the operation and safe clearing procedure for an M16A4 style rifle chambered in .22lr, as presented by Lady Sharpshooter. The guide covers proper shooting techniques using a rest and emphasizes a thorough firearm clearing process after firing.

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.
