Is Your AK Working Properly? DyKem Test.
This guide details a method for testing AK-pattern rifle bolt and trunnion lug wear using DyKem layout fluid. By applying DyKem to critical locking surfaces and cycling the action, users can visualize wear patterns. This technique helps identify potential issues like uneven force distribution between primary and secondary locking lugs, which can indicate manufacturing or assembly problems. The process involves careful application, dry cycling, live-fire testing, and analysis of the resulting wear marks to assess the firearm's mechanical health.
