Abstract
A firearm with barrel interlock system for a rotary mounted quick coupling barrel assembly. In one embodiment, the firearm includes a receiver and barrel assembly rotatably mounted thereto. A bolt carrier supporting a bolt is slidably disposed in the receiver and axially movable into and out of battery with the barrel assembly. The barrel interlock system may include a first barrel anti-rotation locking element disposed on the barrel assembly and a mating second barrel anti-rotation locking element disposed on the bolt carrier that is engageable with the first element. When mutually engaged, the first and second locking elements form a meshed relationship and prevent rotation and removal of the barrel assembly from the receiver. In some non-limiting embodiments, the locking elements may be in the form of a protrusion and complementary shaped recess.
