Abstract
The current system is a method for easily attaching firearm devices to the end of a firearm. The system is used to improve the relative alignment between firearm devices and the bore of the firearm. The system solves the problem of non-uniformity when attaching devices to a firearm, by providing a uniform mounting surface. The system includes three main parts: a muzzle extender, a device, and a clamping method. The extender includes a threaded female receptor for attaching to the firearm muzzle and a clamping surface to be used with a clamping method to attach the device. The system has multiple embodiments including, built in muzzle devices, different clamping methods, and multiple devices to attach to the system.
