If I had to answer this question RJ, I'd be taken back to writing answers during our trade tests when only the CORRECT designation would suffice. Little things that could be misconstrued were also frowned on or marked down. Things such as '......it will only rotate so far...' would be sent back with 'what will? and 'how far' and 'why'................. So you'd write it all up again with '...the trigger will only rotate about the trigger axis pin so far because when pulled, the back of the trigger will ultimately close up against the inner rear radius of the trigger guard. When it is pushed forwards, the rear part of the two ribs will contact the trigger bracket on the Mk1/2-3 and 2 rifle or the inside of the butt socket on the Mk1 and 1/1 rifle.

Then that'd come back with 'pulled........ we don't pull the trigger' and 'What do you mean by 'it'.......... So you'd correct the sentence to read 'squeezed and 'the trigger'.

But it taught you to write technical information in an understandable way. Just called for tea so will answer the main question later!!!!!!!!
