This review investigates concerns about the Palmetto State Armory PSAK-74's locking lugs and firing pin. While trunnion lug wear is found to be within normal AK parameters, a significant issue of primers being punctured by the firing pin is identified, causing light primer strikes and potential reliability problems. The rifle is deemed a 'range toy' until these issues are resolved by PSA.

The Century VSKA AK successfully completed a 5,000-round endurance test, functioning through extreme cold and submersion. While it passed a final headspace test, a rear sling bracket failed. Borescope revealed less erosion than previous models, and internal components showed minimal wear, though the bolt had stabilized deformation and the extractor spring required tuning.

This video demonstrates a practical test of whether firearm heat affects headspace, specifically on an AK platform. Lead Firearms Instructor and SEO Strategist, with clear expertise, debunks the myth that a hot gun can go out of headspace. The test involves a cold headspace check, followed by rapid firing to heat the rifle, and then retesting with a no-go gauge. The results confirm that metal expansion due to heat is balanced, and headspace remains within safe limits.

This comprehensive review by AK Operators Union details the performance of the Century VSKA AK47 after 1,500 rounds, including extreme stress tests like the 'Sand Tornado'. The assessment covers various malfunctions, internal component wear, and headspace stability, providing objective data for potential buyers. The instructors emphasize the importance of rigorous testing to simulate real-world abuse.

This video details critical safety checks for sporterizing a Mosin Nagant M91/30, focusing on headspace and firing pin protrusion. It demonstrates bolt disassembly, extractor removal, and the use of headspace gauges. The rifle passes these essential safety tests, clearing it for further modification and shooting.
