Don't be in a rush to throw away packaging. The clear plastic sometimes makes either a nice rectangular pan,
for parts cleaning and various jobs, the flat plastic is easy to store, and has about a dozen uses. Refrigerated packages many times have plastic wrapped foam rubber, @ 1/2"X 10"X 30", remove the plastic wrap, and double up the foam, it makes a nice seat cushion in a tree stand.
If you have a rifle or shotgun you haul around on a tractor, might want to duct tape those external screws, so you don't lose them running around on the farm.
For anyone trying to get good contrast on front and rear sights, try either using white nail polish as a primer,
then your favorite bright color, or White-out. Also for iron sight contrast, try a small punch, punch out
brightly colored stickers, use tweezers and a small exacto blade to separate the sticker from the backing to use it on your rear sights.
To clean 22 caliber rifles, take twine, run it thru the barrel, and tie it to a can tab. Tie figure 8 knots in the
twine, soak the knots in motor oil or some other cleaner, and pull it thru the barrel, back to front. For larger calibers, tie rags onto the line. Not as thorough as a good home cleaning, but it will get you thru till you get home.
