For as long as I’ve been hunting, I’ve carried a small gun-maintenance kit, and it always contained a set of screwdrivers. I’ve found that you need them very seldom, but when you do, you need them very badly. For example, the last two Ruger Gun Site Scout Rifles I’ve bought have had their rails screwed on in a manner that led me to believe the guy who did the screwing was thinking about Ms. Scarlett Johansson, or possibly Ms. Charlize Theron, instead of the task at hand. Now, do you think that those screws would go loose at home, where I have screwdrivers? No way.
