From the manufacturer
Stern Defense SD AR15 Barrel .45acp 8.5in Black ACPBRL85INCHDA. Our barrels offer an advantage over the competition. Every stern defense barrel throat is machined deeper for a longer free bore to accommodate bullets with a longer ogive. We have found that some common defense rounds jam into the rifling before the round is fully chambered. Some of the barrels on the market do not accommodate this and will potentially result in nasty malfunctions resulting in a round being stuck in the chamber requiring manual methods to clear the malfunction. Note: Barrel comes with locating pin installed.
