American Precision Arms Little Jimmy Brake


The APA Little Jimmy brake is another extremely effective brake. The ports are slightly larger than the APA "Little Bastard" brake and the front has a contour similar to the APA "Fat Bastard"  brake. The brake should be installed by a competent gunsmith since it should be properly timed, contoured and the bore line opened up to match the caliber of the host firearm.
