This video explains the phenomenon of light primer strikes in AR-style firearms, attributing them to the design of the floating firing pin. The instructor demonstrates how a floating firing pin can leave a small dimple on the primer even without a full ignition, which is normal for many AR-15 and AR-10 platforms. It also touches on how some blowback AR systems mitigate this effect.

This review covers the Smith & Wesson Response 9mm AR-9, highlighting its compatibility with Glock magazines and its direct blowback operation. The review details accuracy at 50 yards, features like the polymer handguard and M-LOK slots, and the unique bolt design with a tungsten weight for recoil mitigation. It also recounts a significant out-of-battery discharge incident with the first sample, attributed to a broken detent, and confirms the second sample's reliability after extensive testing.

This guide details how to troubleshoot reliability issues in AR-9 platforms, specifically focusing on magazine feed lip interference with the last round bolt hold open (LRBHO) lever. It involves comparing magazine dimensions using digital calipers to identify the cause of malfunctions, particularly when using ASC or C-Products magazines. The analysis helps determine if a different magazine brand or potential modification is needed for consistent performance.
