This is the optional mission that can be found on Level 6: Morituri Te Salutant.
At about 800m from the Coliseum Objective, there will be a small flight of stairs that are about 10 meters before a small mini-coliseum type building. Go to the right of those stairs to meet Secchi who will then give you the optional mission of signing his rifle. From there it's a pretty linear path that leads to an outpost with some weapons, armor and of course the rifle that needs signing. Achievement pops after a brief cutscene of you signing his possession. Make sure to put your difficulty on tourist and have infinite ammo enabled!
I couldn't find a video that references just this achievement but I did come across a 100% video from Decino that has this section detailed at around the 14:30 mark in case you need more of a visual for this.
