When I purchase a firearm I keep the box/case in my attic and the manuals and reciepts locked up in a fire safe. Many times if you sell a fire it has more value if you have the box. But what about costly optics and accessories. Of course I keep the manual and receipts but is it worth it to keep the boxes and cases. Typically once I mount and plumb a scope or optic it pretty much stays with the firearm in the safe or case. I'm not talking about inexpensive parts like lens covers and such. Most quality part comes in a serial numbered case matching the part. Heck some optics like ACOGs and such come in Pelican cases. Space really isn't an issue. It's not a time consuming matter. And some boxes like the Nightforce boxes just collapse and lay flat. Is it worth keeping the boxes and cases to high dollar items that I'll likely never put the item back in again?
