Overpressure Evaluation of the Knight's Armament Noise Suppressors for the C7 andC3A1 Rifles

摘要

The Diemaco division of Devtek Aerospace was contracted by Directorate of SoldierSystem Project Management (NDHQ) to evaluate the effect of the Knights Armament noise suppressor (serial no. 93506) when used with the C7 5.56 mm rifle and the Knights Armament noise suppressor (serial no. 3001) when used with the C3A1 7.62 mm rifle. Noise measurements were carried out in single-shot mode at a number of locations in the vicinity of the weapons to determine peak pressure levels and impulse durations.
