Why the 10.5-Inch Carbine Configuration Works
The 10.5-inch barrel represents the historical “sweet spot” for compact AR-15 builds. Paired with a carbine-length gas tube, the PSA AR-15 pistol 10.5 carbine 5.56 maintains sufficient dwell time to ensure positive extraction and smooth cycling across standard 55-grain target loads and heavier self-defense rounds.
Ballistic testing from Pew Pew Tactical shows that 10.5-inch 5.56 barrels retain enough muzzle velocity to deliver dependable terminal expansion at typical defensive engagement distances while slashing overall weapon length for faster transitions.
