Evaluating the Quality of Combination Gun's Firing Mechanism

This Master’s thesis deals with evaluation of quality of Brno Combo combination rifle shotgun rifled barrel’s firing mechanism. It contains a proposal of criteria for evaluation of quality of firearm firing mechanisms. It further focuses on using measurement of primer deformation as a means of assessing the quality of a firing mechanism. Based on measurements made using a Focus Variation microscope, various geometrical parameters of fired and failed primers were analysed. The measurement results were processed using ANOVA and regression analysis. Based on output of these analyses, practical recommendations and further research proposals were formulated
