Berettatiger

According to the instructions from Dinzagarms: http://dinzagarms.com/downloads/x39_mag_options.pdf I want to do Option#1 I DON'T WANT TO TOUCH THE RIFLE!!!! NOW THEY TALK IN OPTION #1 about a feeding ramp. I don't know what it is or where it goes. I have compare the factory mag with the AK mag and I dont see any difference or feeding ramp. Please could somebody be patient enough to explain what is the feeding ramp and where it goes. Notice that in Option#1 YOU DON'T TOUCH THE RIFLE!!!
