A quick and hopefully easy question for you ferretfixer, Is the L3A1 and 2 simply a redesignation of the 1919A4, so closed bolt fixed and flexible, and A3 and A4 the rear sear open bolt conversion?
Or, are they as I suspect, A1 and A2 rear sear/open bolt conversions and the A3 and A4 are rear sear/open bolt conversions plus the trigger mod?
I ask as my own A2 has the original profile trigger but is still in the open bolt configuration. I've looked at mant L3A1 to A4 guns (But not been able to examin in detail) and even reference material is contradictory and inaccurate, Ian Skennerton states in his SAIS on the L3 that the A1 and A2 are rear sear conversions and that the A3 and A4 have had trigger conversions plus the rear sear conversions. Many other references state that the A1 and A2 are simply re-designated 1919A4s with closed bolt and the A3 and A4 are the open bolt conversions.
So I am assuming that the A1 and A2 have curved triggers and modified for open bolt and the A3 and A4 have the square trigger mods and open bolt mods. Would this be correct?
Cheers, Chris.
