A noise and recoil suppressor apparatus for high powered rifles includes a tubular body with an inner central cylindrical bore and an outer cylindrical surface. A butt end portion of the tubular body is adapted for attachment to the muzzle end portion of a high powered rifle and the body ...
The purpose of the study is to describe the effect of a suppressor to environmental noise with a typical Finnish rifle shooting range that has a shooting shelter and some noise berms. The noise measurements were carried out at Kyronpelto shooting range situated near Mikkeli in Finland. The ...
Five shots were fired to establish the unsuppressed sound level, after which 10 shots with the suppressor attached were fired under consistent environmental conditions. The suppressors are clearly effective and the attenuation levels reduced the sound levels to under 140 dB in all tests.Acoustics ...
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 ...
