Original cell phone videos provided by Alex who was having an issue with feeding from Metalform mags. I processed the videos by slowing and reversing. With 1 round left in the mag the LRBHO tab was pushing up on the bolt catch, causing feeding problems. The bolt would slap the bolt catch and follower down, causing the round to drop in the mag and jam under the bolt. Trimming the mag follower tabs fixed the problem. This was done in a controlled environment with the FIRING PIN REMOVED to disable the system and prevent any chance of a negligent discharge.
