Whooooooooa there....... Beerhunter is right and the points the doubters make are realistic but the fact is that the trigger was hung on the body to make manufacture AND ASSEMBLING the rifle an easier/simpler task for unskilled labour. The correct assembly of the rifle was a huge bottleneck in manufacture because if the trigger pull-off wasn't correct it had to be fully stripped again and then reassembled, tested and on and on, perhaps several times.
Why Mk1`/2's and 1/3's, Standardisation and ease of assembly at the factory again.
Brian is right (thread 7 line 2-3) in that there is little difference between the Mk1 and 1/2 variants. But that isn't the point. It's not WHEN they are both operating/functioning correctly, it's MAKING them operate/function correctly from virtually new. Adjusting a Mk2 trigger is simplicity itself. Youy can test it fully stripped on the bench. NOT so with a Mk1.
And, please, please please. for the sake of my sanity, patience and diplomacy don't tell me that you can set the trigger pull-offs correctly by tweaking or bending the trigger guard............
Go to the top of the class Beerhunter. But perhaps you should have added the words '.....and assembly by an unskilled workforce' after manufacture
