Abstract: The invention is a suppression device to eliminate flash, noise and smoke, collectively “gas” which is created by explosion of a high-powered rifle hammer striking a bullet, from escaping down a barrel of the rifle so as to expose a shooter's location. The device is physically located nearest to the receiver of the rifle. It operates by machine cutting the barrel to form a diverter which directs the gas into a chamber. Inside the chamber are five concentrically and longitudinal arrayed tubes. The gas travels a longer path than the bullet by passing through the tubes, echoing back and forth until dissipation of the gas.

Abstract: My invention is a rifle noise suppressor comprised of a cylindrical chamber which contains a nested set of baffles concentrically and longitudinally arrayed through the chamber. One end of the chamber is threaded and threads are cut into the barrel of a rifle to permit the noise suppressor to be screwed into place. The chief advantage of the concentrically arrayed baffles is a shorter chamber, approximately one-half the length of a typical noise and smoke suppression device, yet able to achieve equal noise and smoke suppression by causing the escaping gases following the explosion of the bullet being fired to travel farther within the suppressor chamber.

Abstract: Rifles, such as the AR-15, can be equipped with four connected rectangular plates, referred to as a “Quad Rail.” The purpose of the quad rail is to accommodate shooter's accessories such as high powered scope, night or infrared scope, battery(ies), laser pointer, optical range finder, and single hand grip or a bi-pod. Once the shooter selects the accessory, he or she is stuck with it, since replacement of the accessory is time consuming. My invention improves the quad rail by allowing the shooter to rotate it under conditions in the field without any tools. Rotation in the field permits rapid deployment of the accessories and avoids the need for re-calibration. The shooter's accessories are all mounted on the quad rail, such that through rotation of the quad rail or series of quad rails, a different accessory or combination of accessories can be immediately utilized.
