Quick Tip: Pistol Caliber AR-15 Buffer Weights
This video from Brownells focuses on the crucial topic of buffer weights for Pistol Caliber Carbines (PCCs) built on the AR-15 platform. Expert Caleb explains why PCC buffers are heavier than standard rifle caliber buffers due to the blowback operating system. He details typical buffer weights for 9mm, .40 S&W, .45 ACP, and 10mm Auto, emphasizing the need for even heavier buffers when using suppressors. The video also touches upon the variation in PCC buffer lengths.
