WWSD2020 - KP15 First Field Trials

This entry details the GWACS monolithic polymer lower receiver, a key component of the WWSD project, emphasizing its weight reduction benefits and durable, integrated design. It highlights the advantages of the fixed M16A1 length stock for ergonomics and user comfort, and its ease of modification due to its polymer construction. The information is presented with the authority of experienced firearms instructors.

This video demonstrates the extreme reliability of the WWSD 2020 AR-15, developed by KE Arms and Brownells, under harsh environmental conditions. Instructor Karl Kasarda, with high authority in firearms testing, submerges the rifle in mud twice, including direct contamination of the action, and fires it successfully after each test. The WWSD 2020, featuring a KP-15 polymer lower receiver, proves its capability to function even when heavily soiled.

This video tests the durability of polymer AR-15 lower receivers against an aluminum counterpart. The primary failure point identified for polymer lowers is the threaded buffer tube receiver area, which can strip or crack under stress. While polymer lowers are significantly cheaper, the testing demonstrates a substantial compromise in robustness compared to aluminum receivers, making them unsuitable for demanding use or abuse.

This video provides an in-depth look at the KE Arms KP-9, a 9mm polymer lower receiver. Featuring insights from Ian McCollum and Russell Phagan, it details the design, compatibility, and unique technical aspects of the KP-9, including its Glock magazine integration, adjustable ejector, and blowback bolt mechanics. The discussion highlights practical considerations for builders and shooters looking to assemble a 9mm AR-15 platform.

This entry details the performance of the WWSD2020 rifle, specifically the KP-15 polymer lower, during a rigorous full-auto torture test. Expert analysis from InRangeTV highlights the rifle's reliability over 210 rounds, the thermal resistance of its polymer components, and the effectiveness of its specialized parts like the JP Silent Captured Spring and Faxon barrel under extreme conditions. The test demonstrates the structural integrity and heat management capabilities of the build.

This entry details the 'What Would Stoner Do 2020' (WWSD 2020) project, a collaboration led by Ian McCollum of Forgotten Weapons and Karl Kasarda of InRangeTV. The project aims to realize Eugene Stoner's original AR-15 design principles of lightweight reliability using modern materials like carbon fiber and polymer, featuring an innovative integrated polymer lower receiver. Brownells serves as the exclusive distributor for the complete rifle, produced in partnership with KE Arms.

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.
