Thanks for the info guys! I'm not much of a carpenter; do you think it's likely that I'll be able to find a new upper handguard to buy? Shoot, if I had to, I might just buy the whole stock set. The stock itself is in "fair" condition, so I am considering trying to refinish the whole thing or buying a new stock.
On a separate note, I shot 50 rounds through it today. Wonderful shooter. I did have a LOT of hangfires though. I was using some unmarked milsurp ammo from the LGS. Do you guys know of any particular ammo to stay away from when I'm looking for more? Is the 8mm ammo somehow more susceptible to hangfires than 7.62x54? I haven't had a single problem with my Mosin.
