Domestic Burmese G3s: BA64 Rifle and BA-72 Carbine

This review critically examines PTR Industries' value proposition compared to Heckler & Koch, tracing PTR's evolution from using surplus parts to in-house manufacturing with MIM components. The analysis highlights significant quality control issues in modern PTR rifles, including soft barrels, structural flaws in MIM parts, and misaligned components, questioning their long-term durability and value.

This video compares the FN FAL (G1) and H&K G3 battle rifles, with John Keene favoring the G3 for its lighter weight and Ian McCollum preferring the FAL for its left-hand friendly charging handle. Both rifles are acknowledged as top-tier military firearms with extensive service histories. The discussion highlights specific ergonomic differences, such as the FAL's charging handle placement versus the G3's overall lighter carry weight.

This review focuses on the Heckler & Koch G3 battle rifle, comparing it to the FAL and highlighting its manual of arms. The G3 lacks a last-round bolt hold open, requiring an 'HK slap' to chamber a round. The .308 caliber recoil is described as abrupt but satisfying during live fire.

The HK11 is a specialized variant of the G3 battle rifle, incorporating light machine gun features. It utilizes standard G3 magazines but was designed for drums, and features LMG-specific sights, a bipod, and a carry handle. A key design element is its quick-change barrel system, enhancing its utility as a support weapon.

This review showcases the PTR GI, a clone of the H&K G3 rifle, chambered in .308 Winchester/7.62 NATO. The video demonstrates proper loading of a 20-round steel magazine and weapon manipulation, including chambering a round. A live-fire session from a benched position highlights the rifle's recoil and cycling against a steel target.

This review details the Portuguese FMP HK21, a belt-fed light machine gun derived from the H&K G3 rifle. Key differences include a specialized feed unit and a modified bolt carrier with a cam track to operate the belt feed mechanism. The HK21 maintains significant parts commonality and training similarities with the G3, simplifying logistics and user transition.

This video details the unique 'French Finger Trap' issue with the MAS-36 rifle's bayonet, where two rifles can become unintentionally locked together. A 1951 French arsenal memorandum identified this problem, proposing a simple modification to the bayonet handle. Drilling a small hole allows a tool, like a firing pin, to depress the internal spring, enabling the separation of locked rifles.

The M134 Minigun is a scaled-down 7.62 NATO rotary cannon, requiring 24V DC power and consuming 1.5 kW. Its high rate of fire (3,000+ RPM) is essential for aircraft engagement windows. The complex delinker mechanism is critical for feeding ammunition, and practical hand-held use is impossible due to weight and recoil. Live fire demonstrates rapid ammunition consumption and the need for indirect aiming.

The H&K G11 is a revolutionary prototype assault rifle designed in the late 20th century, notable for its caseless ammunition and unique rotating drum bolt mechanism. Despite advanced features like a 2000 RPM burst fire rate and integrated optics, its development was ultimately halted by geopolitical shifts and cost concerns.

This video demonstrates the assembly and live-fire of the German 1936 pattern light mortar (L.Gr.W.36). It highlights the mortar's leveling mechanism for accuracy and the difficulty in visually tracking its 50mm projectiles after firing. The content showcases historical military hardware and its operational use.
