This last few threads has been very interesting because one small student project (in the days of L1A1';s and WO Dxxxxs and Col Txxxxx) on the design course was to illustrate to a convening Board of Enquiry how a fatal accident (not a REAL accident of course, just a mock-up to get the brain cells working.....) could not have occurred given the explanation. There were three groups. 1 group to give a written explanation. 1 group to give a blackboard/flip chart explanation while another gave an 'as-is' explanation using a sectioned breech block and carrier. It's simple to slot a BB but it's very difficult to cut or machine the carrier! Got to be annealed first and cut or ground carefully. Anyway............. I did something similar with an SA80 at Warminster and the 'working guts' of the demo rifle were in the lecture room when I left.
