DIY Rifle 'sight-in' bench for <$20 in materials.
Having a bench increases the probability that you can accurately 'sight-in' a rifle. If you can afford the materials (<$20 at the chain hardware stores) and have the necessary tools as well as the construction skills, you can make your own bench. It is also light enough for one man to carry. Then all you need is about 100 yards of open space, some targets, and a good backstop. (You are responsible for following ALL laws in your area.)
Take a look at the video. Any feedback (good OR bad) will be appreciated.
NOTE: The design of the bench utilizes the weight of a person on the seat to increase stability.
