Testing the RM338: The 50 CAL Replacement with Unbelievably Light Recoil

This guide provides an overview of the SIG Sauer MG338 (M250) machine gun, drawing on insights from Cory McQuilkin, a Defense Product Manager at SIG Sauer and former Special Operations member. It covers key operational features such as the ambidextrous controls, side-opening feed tray, quick-change barrel, and innovative loading systems. The information emphasizes the weapon's design to overcome shortcomings of legacy systems and its readiness for combat evaluation.

This expert overview of the SIG Sauer MG 338, presented by Jason St. John, Director of Defense Strategies at SIG Sauer, details its operational features. Key takeaways include its .338 Norma Magnum caliber for enhanced lethality, a weight advantage over the M240, advanced recoil mitigation, ambidextrous controls, a unique side-loading mechanism, and a quick-change barrel system. The design prioritizes optics compatibility with a side-opening feed tray.

This entry details the SIG Sauer SL Mag 338, a next-generation machine gun showcased at SHOT Show 2020. Expert insights from SIG Sauer and RECOILtv highlight its advanced features, including a quick-change barrel, 3D-printed suppressor, ambidextrous operation, and a design intended to surpass legacy systems in weight and performance. The weapon is noted for its potential adoption by US Army/SOCOM for evaluation.

This expert guide details the SIG MG 338 machine gun, highlighting its advanced features for extended range engagements. The video, presented by SIG SAUER, Inc., emphasizes its lightweight design (under 20 lbs), folding stock, ambidextrous controls, quick-change barrel, and impressive 2,000-meter range. It also notes the 600 rounds per minute rate of fire and enhanced recoil mitigation, positioning it as a high-performance military-grade weapon.

This video provides an expert-level comparison of the Combloc RPD and PKM machine guns, highlighting their distinct design philosophies and operational features. The host, demonstrating high authority and hands-on experience, details the RPD's milled receiver and AK-like operating system versus the PKM's stamped steel construction and lighter feel. Key differences in caliber, charging handles, and barrel systems are thoroughly explained.

This entry details the KAK Industry Water-Cooled AR-15 system showcased at Shot Show 2026. The design integrates the barrel, gas block, and gas tube within a water jacket, inspired by historical 1917 cooling methods. This system is engineered to maintain component temperatures below 212°F, theoretically allowing for indefinite firing as long as water is replenished. The system can operate in belt-fed or semi-auto modes.

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.
