The AR15 (WWSD) is more reliable than the AK.
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.
