So, it turns out that Neil of The Wirksworth Gunroom was looking after a very interesting piece that I had no prior knowledge of: BSA's competitor to the trials which resulted in the adoption of the 5.56mm L98A1 Cadet GP monstrosity rifle that I suffered as a CCF cadet at school back in the 90's. This rifle succeeded the .303 Lee-Enfield No.4 in Cadet use, and was horrible. Not sure this BSA competitor is much better though, honestly!
Finally going over to the semiauto L98A2 was definitely a good idea...
