Incorrect, this was not an official modification. That being said, I have seen this done to cadet DP No 4's as well.....seeing they were DP's, I chose to look the other way so to speak....
There was a semi-pistol grip stock made in WWII for the LB snipers. Brits didn't adopt it because it was Canadian, sniff, sniff, despite all the people who tried it over there, loving it. Same as the C67 scope, all kinds of games were played to make it 'ineligible'. This is from Clive Law's Without Warning, by the way.
