MUZZLE DEVICES – EFFECT ON ACCURACY, PRECISION AND VELOCITY
I spent a decade designing and testing small-arms ammunition in the defence sector, writes Hexagon Ammunition’s Paul Bradley. During that time we faced many confounding variables. With no apparent change to build standard or materials we would find performance parameters shifting. We discovered many variables after hours of head scratching that we had not previously accounted for. One of those was the humble muzzle device – and surprisingly it had little to do with barrel harmonics.
