This guide details the disassembly and internal analysis of the custom-built RN-45 firearm by Royal Nonesuch, as presented by professional firearm designer Mark Serbu. It covers component identification, internal mechanism critique, and diagnostic insights derived from high-speed footage, highlighting the firearm's unique construction and operational characteristics.

This guide details the field stripping process for the Valkyrie Arms M3A1 Semiauto, a reproduction of the M3 Grease Gun. It highlights the disassembly into upper and lower receivers, identification of the AR-15 fire control group, and examination of the bolt and recoil assembly. The process is presented with a focus on understanding the internal mechanics and modifications made for semi-automatic civilian compliance.

This guide covers the operational aspects and integrated tools of the M3A1 Grease Gun, as demonstrated by Iraqveteran8888. It highlights the weapon's historical context, design features like the multifunctional wire stock, and its intended use as an area weapon. The information is presented with a high degree of authority, drawing on deep technical knowledge of WWII small arms.

This video details a field modification performed on an M3 Grease Gun submachine gun. When a soldier's original crank handle was damaged in combat and no replacement was available, an ordnance sergeant cut a slot in the receiver and installed a crude bolt handle to restore functionality. This demonstrates a resourceful, albeit basic, repair technique used in the field.

This guide explains why the M3 Grease Gun did not use Thompson submachine gun magazines, despite potential logistical benefits. Expert Ian McCollum details how the M3's design prioritized cheap, rapid mass production using stamped sheet metal and a simple single-feed magazine, contrasting with the Thompson's complex T-shaped lug requiring a milled receiver. This fundamental difference in manufacturing and retention mechanisms made cross-compatibility impossible.

This video features Edwin Sarkissian, an experienced firearms instructor, conducting a unique bullet penetration test. He uses 12 Ozark Trail 12-inch cast iron skillets to determine how many rounds from various calibers and firearms, including 9mm, .45 ACP, 500 S&W Magnum, 7.62x39mm, 5.56mm, 5.7x28mm, and 12 Gauge slugs, can penetrate the cookware. The results offer practical insights into the ballistic performance of different ammunition types against a common household item.

This video from Edwin Sarkissian provides an expert-level demonstration of the Serbu BFG-50A rifle's capability against a railroad track. Sarkissian, a high-level firearms enthusiast, showcases the .50 BMG caliber's power with various ammunition types, including the specialized Raufoss Mk 211 Mod 0, highlighting its penetration through thick steel. The content offers valuable insights into terminal ballistics and the performance of heavy caliber rounds.

This video demonstrates a unique application of the X Products Can Cannon, a gas-operated launcher compatible with AR-15/M16 lowers, to launch an M67-style fragmentation grenade using .223 Blanks. Expert experimentalist Edwin Sarkissian showcases the process of loading and firing the device towards a frozen lake, highlighting the launcher's ability to hold the grenade's spoon in place until firing. The demonstration results in a significant explosion and ice shatter upon impact.

This guide details a ballistic test comparing a .50 Cal Spotter round against a 1.25-inch thick bulletproof glass panel using a Serbu BFG-50A rifle. The test, conducted by firearms enthusiast Edwin Sarkissian, demonstrates the significant destructive potential of specialized .50 BMG ammunition, highlighting differences in impact effects between incendiary spotter rounds and standard FMJ rounds. The expert-level demonstration emphasizes the importance of understanding ammunition types and their performance against protective materials.
