This guide details the initial zeroing and inspection process for the Palmetto State Armory GF3 AK, as demonstrated by Rob Ski. It covers adjusting the front sight, assessing the hammer-forged components (bolt, carrier, trunnion), inspecting build quality, and performing a crucial headspace verification using a 'No-Go' gauge. The review highlights community-requested features and provides an objective look at the rifle's construction.

This comprehensive 1000-round review of the Palmetto State Armory PSAK47 Gen 2, presented by Rob Ski, offers an objective assessment of its performance and build quality. Ski, a recognized expert in AK-platform testing, details accuracy under heat stress, zero malfunctions across various ammunition, and solid magazine fitment. While noting minor cosmetic quality control issues, the overall verdict is positive, with the rifle exceeding expectations. Further testing is planned to 5000 rounds.

This guide details the disassembly and internal inspection of the Palmetto State Armory PSAK47 Gen 2 rifle, as demonstrated by an expert from AK Operators Union. It covers key components like the billet-made bolt, free-floating firing pin, horizontally riveted bolt carrier piston, and the AKM-style billet front trunnion. The inspection highlights manufacturing quality, potential areas for improvement like a slightly loose safety lever, and confirms the rifle's construction aligns with established AKM designs.

This comprehensive analysis details the findings after a 5000-round durability test on the Century Arms RAS47, conducted by an expert in the AK-47 community. The review highlights significant component failures, including cracked furniture, broken sights, deformed bolt lugs, and loose rivets, leading to the rifle being deemed unsafe due to excessive headspace. Despite these critical issues, the rifle maintained accuracy with an optic when iron sights were non-functional. The expert strongly advises users to perform regular headspace checks using Go/No-Go gauges.
