So I just got a Glenfield Mod.30A (in other words a Marlin 336), and I love it, even though I have yet to shoot it. However there is one issue I found with it. Nowhere to mount a sling. Would one just put to sling swivels into the forend and butstock? Or is there a special barrel band or end cap version available in Canada? (Hoping to have it in time for the second week of the deer hunt)?
