Abstract
The invention allows use of the M2 universal breech for EPVAT tests carried out on calibre 5.56, 7.62 and 9 NATO ammunition, with the possibility of measuring the actual operating time free from systematic errors. This is achieved with a new trigger device electrically insulated from the breech body. Said device has a plastic ring which, pushing the firing pin into contact with the ammunition cap, eliminates the delay due to travel of the firing pin from measurement of the operating time. The firing pin has been lengthened and passes through the whole breech block; the thickness of the barrel locking ring has been reduced so as to allow extraction from the muzzle of EPVAT calibre 9 NATO barrels. <IMAGE>
