PSA's PA-15 in .300 Blackout follows the same value formula as their flagship 5.56 model. The 16-inch nitride barrel handles both supersonic and subsonic loads. The carbine-length gas system is tuned for 110–125gr supersonic ammunition; an adjustable gas block is recommended for reliable subsonic cycling. At PSA's price point, this is the most accessible entry into .300 BLK for budget-conscious suppressor owners.
