Shooting the Worlds Shortest AR15
This video tests the functionality and ballistics of an extremely short 4.75-inch barrel AR-15 in 5.56 NATO. Despite common concerns about reliability with short barrels, this build cycles reliably, though it produces a massive fireball and concussion. Velocity and energy are significantly reduced compared to longer barrels, impacting terminal ballistics, but it remains lethal. The extreme muzzle blast poses a significant safety risk if hands are held too close.
