I'm scouring the book Ivan's War to find the story of the guy who had to walk to the front after being called up, and I thought I remembered he didn't have a weapon, but honestly it doesn't really specify. He started his journey at a barracks, so I'd assume he probably did have his rifle, but not too sure.
A lot of recruitment stations were set up in school or suchlike, so they'd stamp your papers say you're 'in the army', and that was all you got. No beds, no food, but they all somehow found Vodka...
Especially in June 1941 it was absolute chaos and the recruitment systems weren't ready for the massive influx of patriotic volunteers.

This volunteer was told to join his unit in Lvov, starting in Kiev (544 km), but was given no instructions or provisions for actually getting there. Failure to show up would be desertion though... so he scrambles on to a train, shoving other recruits and people out of the way, but falls off, thankfully his fall was broken by someone else who had also fallen off, otherwise he probably would have broken his back.
