The video highlights how dual ejectors significantly reduce the likelihood of ejection failure compared to single ejectors. However, it also notes that these bolts can require buffer and spring tuning due to increased extraction force, potentially necessitating lighter buffer weights or springs for optimal performance. The instruction is delivered with expert-level detail, explaining mechanical failure modes and system interactions.
