AR15 Barrel Length and Velocity - WWSD
This video from InRange TV discusses the impact of AR-15 barrel length on projectile velocity, specifically for .223/5.56 ammunition. The presenter clarifies a correction regarding the specific ammunition used (PMC Bronze, not M193) but emphasizes that the core point about barrel length and velocity remains valid. The video demonstrates and discusses the velocity differences observed with 14.7, 16, and 20-inch barrels, highlighting the importance of sufficient velocity for the round's effectiveness.
