A bolt carrier impingement device for a firearm has a body including a rearward facing surface. The rearward facing surface of the bolt carrier impingement device abuts the forward facing surface of the bolt carrier, thereby transferring all rearward force imparted to the front of the bolt carrier impingement device through only the forward facing surface of the bolt carrier. The rearward facing surface of the body may be a notch and the forward facing surface of the bolt carrier may be a buttress. The bolt carrier may include a cam aperture formed through a top surface rearward of the forward facing surface. A forward most portion of the impingement device may terminate in front of the cam aperture. A bottom surface of the body may form a slot that forms an arch over the cam aperture.
