This video provides an in-depth look at the KE Arms KP-15 monolithic polymer lower receiver, a key component of the WWSD2020 rifle. Speakers Karl Kasarda, Ian McCollum, and Russell Phagan detail its design philosophy, manufacturing process, and compatibility. They emphasize its robust construction, designed to overcome traditional polymer firearm limitations, and discuss its integration with standard AR-15 components. The discussion also touches on ATF compliance, material science, and finishing techniques suitable for the polymer construction.

This video showcases new firearm products from Midwest Industries, KE Arms, and Wilson Combat. Paul Levy from Brownells demonstrates the Midwest Industries Professional Armorer's Wrench, a multi-tool designed for AR-15 and AR-308 builds, repairs, and maintenance. It includes various wrench functions, a hammer, and a bottle opener. The video also highlights the Wilson Combat Ranger-Contour Match-Grade AR-15 Barrel in 5.56 NATO with an intermediate-length gas tube for improved reliability and recoil management. Additionally, the Midwest Industries AR-15 M-Series Two-Piece Drop-In Handguard is presented as an easy upgrade for older A1/A2 rifles to a modern M-LOK tactical handguard. Finally, the KE Arms KP-15 Trap Door Buttplate is shown for the KP-15 lower receiver, offering storage access.

This video introduces a custom firearm build project centered around the KE Arms KP-15 monolithic polymer lower receiver. The builder plans to create a Dissipator-style rifle, a less common configuration, utilizing an AT3 upper and a Del-ton barrel with a rifle-length gas system. The description highlights the creative use of modified Magpul MOE SL handguards to achieve the desired retro-modern aesthetic and performance.

This guide details the evolution and assembly concepts of monolithic polymer AR-15/M16 lower receivers, from Colt's early experiments to modern designs like the KE Arms KP-15. It highlights key design changes, manufacturing techniques like linear vibration welding, and improvements in strength and ergonomics. Instruction is provided by Ian McCollum, a recognized expert in firearm history and mechanics.

This video details the development of the WWSD2020 Mk3 Lower, a modern polymer AR-15 receiver. It highlights the project's origins, the evolution of polymer lower designs, and the partnership with KE Arms for manufacturing. Key improvements include an optimized flared magwell for PMAGs and D60s, enhanced ergonomics, and the addition of M-LOK slots. The content is presented with high authority, drawing on deep knowledge of AR-15 history and manufacturing processes.

This guide details how to clear common malfunctions on an AK-74 platform rifle, specifically when heavily fouled with mud. Expert instruction from Karl Kasarda demonstrates advanced techniques for dealing with failures to go into battery, feeding issues, and stuck chambers. The video emphasizes the importance of understanding mechanical tolerances and performing thorough cleaning after such extreme environmental testing.

This guide details the historical method of igniting and deploying 18th-century grenades, as demonstrated by Karl Kasarda of InRangeTV. It covers the preparation and use of a slow match to ignite the external timed fuse of a replica grenade. The video emphasizes that this is a replica and stresses the extreme danger and illegality of handling live explosives.

This guide details the proper application of a Gaza-style or CAT tourniquet, as demonstrated by Karl Kasarda on InRangeTV. It emphasizes initial strap tightness before windlass use for effective hemorrhage control and occlusion. The instruction highlights the importance of securing the windlass and managing patient pain during application.

This guide details the historical loading process for the 1836 Colt Paterson revolver, as demonstrated by Karl Kasarda. It covers the unique disassembly required, the precise powder charge and projectile seating using specialized tools, and the capping procedure. The instruction emphasizes a high level of expertise due to the intricate and period-specific nature of the task.
