Homemade Grenade Launcher? *Can Cannon + Flashbang* (Thanks @DeskPop )

This video delves into the history and technical aspects of Colt's four-way enhanced rifle fire control group, a system offering Safe, Semi, Auto, and Burst modes. The expert instructor, with extensive experience at Colt, details the evolution of the burst cam, patent information, and specific rifle models that utilized this complex mechanism. It highlights practical challenges and historical context, including issues faced by the Greek Army and the eventual discontinuation of the program.

This guide outlines how to build an RPK-inspired rifle on an AR-15 platform. Key modifications include a 24-inch barrel for accuracy, a large muzzle brake for rapid follow-up shots, a bipod for stability, and a fixed stock for consistency. A side-charging upper is also suggested for easier reloading.

This guide details the process of lapping an AR-15 receiver to ensure proper barrel alignment for improved long-range accuracy. Instructor Stephen Caleb from Brownells explains that receiver faces can be slightly out of alignment, leading to barrel runout. The process involves using a specialized lapping fixture and aluminum oxide lapping compound with a drill to create a perfectly flat receiver face. This ensures the barrel seats flush and square, critical for precision shooting beyond 500 yards.

This guide details how to reload budget-friendly 223 Remington ammunition using Berry's 55 and 62 grain bullets and Accurate 2520 powder. It covers component selection, progressive press setup, load data considerations, field testing with a chronograph, and cost analysis, highlighting significant savings by reusing brass. The presenter, Serena, brings over 10 years of competitive service rifle experience and extensive behind-the-scenes work at Ultimate Reloader.

This guide details the process of building a retro AR-15 clone inspired by early 2000s SWAT firearms, focusing on the 'SWAT gun' build. Key elements include sourcing a police trade-in Colt AR-15, integrating a Surefire handguard with a built-in light, and mounting a 1.5x ACOG optic. The emphasis is on aesthetic authenticity and the 'cool factor' of early tactical accessories.

This guide details 17 lesser-known features and maintenance hacks for common firearms, including AK-47/74 buttstock cleaning kits, S&W M&P frame tools for disassembly, Mossberg magazine dowels for capacity control, and status indicators on various pistols. The instruction emphasizes utilizing manufacturer-provided tools and understanding specific firearm mechanisms for safe operation and maintenance, drawing on expert knowledge of firearm platforms.

This video presents a humorous skit emphasizing the critical importance of wearing eye protection at the shooting range. It visually demonstrates a handgun malfunction and uses a relatable, albeit exaggerated, scenario with a spent casing to highlight the potential dangers of inadequate eye safety. The creator, experienced in firearm handling and tactical gear, reinforces this essential safety message.

This video features a 'bulletproof' test where a tree is used as a ballistic medium to test various calibers from .22 LR up to .50 BMG. The Civilian Tactical host, demonstrating high-level firearms expertise, shows that even powerful rounds like .50 BMG can be significantly stopped by a dense tree, with none of the tested rounds achieving a complete pass-through. The test highlights the surprising terminal ballistics of different ammunition types against natural barriers.

This video from Civilian Tactical explores the concept of using a human body, simulated with ballistic gel, as a suppressor. The host fires a Derya Arms .22 rifle directly against a ballistic gel head and block, noting the shot sounded 'dead silent.' The experiment demonstrates the penetration depth of a .22 LR round through the simulated head and into the gel block.

This video demonstrates a ballistic test on a Belgian M1 steel helmet, evaluating its resistance against various calibers from birdshot to .223. The test, conducted by Civilian Tactical Host, shows that the helmet is not bulletproof against common handgun and rifle rounds like 9mm and .223. The host's energetic and demonstration-oriented style, coupled with expertise in tactical gear, provides a clear assessment of the helmet's limitations.
