Is the MK18 obsolete?

This video from Yee Yee Life features an experienced individual testing the bullet-stopping capabilities of a 100-pound lead block against various calibers, from .22LR up to .50 BMG. The test includes firearms like Glocks, Rugers, Desert Eagles, AR-15s, FN SCARs, and Barrett rifles, demonstrating penetration levels and the effectiveness of lead as a ballistic material. The results show that while lead blocks can stop many common rounds, high-powered calibers like the .50 BMG can penetrate significantly.

This video from Shark Coast Tactical demonstrates the sound signature of the Ridgeback Defense Co. Rhino X suppressor on an AR-style rifle. Audio recordings were captured at various distances (next to shooter, 50 yards, and 100 yards) to illustrate the suppressor's effectiveness in reducing perceived noise levels in an outdoor shooting range environment. The FDE-colored rifle with an optic is shown during firing sequences.

This guide details advanced scanning and situational awareness techniques for tactical shooting, emphasizing the importance of looking beyond the target and through optics. Instruction from GBRS Group experts highlights how to train for real-world scenarios where peripheral vision and threat assessment are critical. The techniques focus on developing muscle memory for effective scanning after every engagement.

Boondock Ballistician critically analyzes claims of 'record-breaking' 5.56mm ammunition, particularly from Shell Tech and Badlands Munitions. The expert instructor debunks inflated velocity and pressure figures, emphasizing the dangers of misinformation for reloaders and highlighting that standard brass-cased ammunition can achieve similar velocities within safe pressure limits.

This video satirically explores the common misconception that a longer barrel is always superior, even in CQB scenarios. An employee at Louisiana Firearms insists on a 20-inch AR-15 for 'optimal powder burn,' dismissing a customer's practical concerns about maneuverability with shorter barrels. The customer's frustration highlights the disconnect between theoretical performance and real-world application for specific use cases.

This video provides an expert assessment of the Mk18's relevance in 2026, detailing its pros and cons. The speaker, demonstrating experienced knowledge, discusses critical factors like velocity, fragmentation range, dwell time, and effective range limitations. Recommendations are made for optimizing performance and considering alternative barrel lengths for specific needs.

This guide details the proper technique for safely loading the M1 Garand, specifically addressing the common 'Garand Thumb' phenomenon. It emphasizes maintaining downward pressure on the en-bloc clip during loading to prevent the bolt from slamming forward prematurely. Expert instruction from Garand Thumb highlights this as a key safety measure for new shooters.

This comprehensive review of the Russian Altyn helmet, presented by Garand Thumb, details its construction and ballistic performance. The helmet features a 3mm titanium shell with an aramid liner, rated for pistol and fragmentation threats. Testing reveals it stops 9mm and .44 Magnum rounds but fails against rifle calibers like 5.56x45mm and 7.62x39mm. Despite its robust construction for its intended role, its significant weight and lack of rifle protection are noted as drawbacks compared to modern alternatives.

Garand Thumb, a recognized subject matter expert in tactical equipment, critically assesses the effectiveness of ballistic face masks. The video details rigorous testing using realistic ballistic dummies and various firearms, from handguns to rifles, to measure projectile stopping power and backface deformation. The conclusion highlights significant risks associated with these masks, primarily due to severe deformation, suggesting they are often 'gimmicky' and less effective than traditional head protection.

This guide details the correct technique for loading the M1 Garand rifle, specifically addressing how to avoid 'Garand Thumb.' It emphasizes the 'bladed hand' method, a crucial technique for safe and efficient loading demonstrated by the speaker. Proper execution involves a swift, decisive motion to seat the en-bloc clip while protecting the thumb from the forward-moving bolt.
