Carbine vs. Mid-Length Gas System
This guide, presented by a GUNBROS speaker with high authority on AR-15 mechanics, details the trade-offs between carbine-length and mid-length gas systems for a 14.5-inch barrel AR-15, exemplified by the Radian Model 1. Mid-length systems offer reduced recoil and parts wear due to lower pressure and shorter dwell time, while carbine-length systems provide enhanced reliability in adverse conditions.
