Smyth Busters: Matching AR-15 Gas System to Buffer System
This Brownells video features Gun Techs Steve Ostrem and Caleb Savant debunking the myth that an AR-15's gas system length must match its buffer system length. They explain that as long as the gas system provides sufficient gas to reliably cycle the bolt carrier, the buffer system's operation remains consistent. The video touches on situations where buffer weight might need adjustment to achieve reliable cycling, offering insights into AR-15 mechanics and customization. Viewers are encouraged to share their opinions and any overlooked points in the comments.
