This review examines the Riley Defense RAK47 'Krink' after 1,695 rounds. The presenter notes initial concerns about premature wear on bolt lugs and the carrier, which were addressed by Riley Defense. A significant issue encountered was a failure to charge after magazine insertion, later diagnosed as a fouled gas block due to running the firearm hard and suppressed. The review also touches on rust concerns potentially linked to corrosive ammunition. Despite initial wear, the firearm's performance stabilized after returning from Riley Defense, with no further advancement in wear observed.

This comprehensive evaluation from T.REX ARMS details a 5000-round test of the PSA JAKL, focusing on reliability, accuracy, and training methodology. Expert instruction covers breaking down complex shooting courses into isolated drills, identifying and rectifying common malfunctions and component issues like loose barrels and gas block problems, and performing accuracy assessments. The evaluation highlights the JAKL's performance, value, and compares it to traditional AR-15 platforms for training efficiency.

This YouTube video features Mike from CMMG addressing technical questions submitted by viewers to their Tech Support department and social media. The video covers topics such as the research and development time for Radial Delayed Blowback, whether a new BANSHEE needs tuning when suppressed, buffer weight considerations for 300BLK with a suppressor, and the normalcy of wear on Radial Delayed Blowback bolt lugs. The description also promotes signing up for the CMMG Insider newsletter and directs viewers to their website and Instagram.

This video from Palmetto State Armory demonstrates the typical wear patterns expected on an AK-47's bolt and trunnion after firing approximately 1000 rounds. It highlights that minor wear and polishing on the bolt lugs and trunnion are normal during the break-in process and do not indicate a compromised rifle. The process involves using headspace gauges to track changes as rounds are fired.

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.
