AL 2 manual

[mkfromnm]

All, I have posted before on this and if I am doing something wrong please tell me. I had asked if anyone knew where to get a manual for a Beretta AL2. I had some good suggestions including going to Beretta and some other sites. I found some close but not quite manuals. I was wondering if any of our experts in Shotgun forums could tell me which model would be closest to the AL2. It looks like almost all of the 300 series are quite similiar but which is closest?
