Learning a lot about firearms will make you a very valuable individual for a multitude of other positions..
and when I say a lot about firearms, I mean you need to know how to -
Calculate in atleast 3 different ways - distance
calculate velocity in as many different ways as you can, including reading the labels on ammo boxes
calculate the weights of various different objects
Use these skills to calculate where the bullet will hit, at what time, and what was the path it took during flight?
How high (or low) was it at 25 yards when you were shooting at 200 yards?
Take firearms apart, not just one, not just the ones you own, but all you encounter. This builds a problem solving aspect, and improves observational skills, in the event you were actually trying to improve and not blindly observing a series of events you don't actively try to understand.
Get good at this, and you can assemble anything. It's all the same stuff, from guns to drills to computers and cell phones. The same skills for detail stripping/modifying firearms are used for most everything else.
Learning about firearms teaches you how to learn about other subjects. Become awesome at learning facts about firearms, how they function, why they're made, etc etc and you'll notice that in other, similar subjects you are just as awesome there too.
Become good at the logistical aspect of firearms, too. Positioning and placement of your firearm for ready access during various different activities, such as crawling, rolling, resting in inopportune positions, etc. These skills you develop by making the way you carry your firearm comfortably while maximizing your desired results is obviously invaluable for everyday tasks such as driving, walking, etc etc, as well as branching into deeper aspects of your gear, such as your boots.. You'll have a more keen sense of what kind of boot you actually need, and the labels on boots and other products are moreso irrelevant than ever before. You'll no longer look for the most convincing "This is best" tag, but instead have a built in knowledge bank ready for valid and accurate assessment of a product's quality including strengths and weaknesses.
My goal is to -
use other jobs to fund a personal manufacturing facility for prototype firearms and other tools which I then prepare to manufacture on a large scale as a career.
It's my opinion that the firearms industry is terribly mismanaged, and is stagnant. My goal is to replace as many of the current manufacturing trends as possible. Which bearing witness will reveal, these trends produce a large amount of incomplete or failed products. My intent is to make the manufacturing process also the quality control aspect. This is a difficult procedure to create, but its implementation should be fairly straight forward. I, however, do not ever want to hear of my product being anything less than perfect. The need for an automated QC process that can produce identical copies is necessary because the alternative involves a person performing his own inspection and refining from there. Humans make mistakes. That's unacceptable to me.
From there, I will make a more convenient, and trustworthy firearm for the roughest conditions this world has to offer.
You can feel what I'm talking about.. Think about the rangers and their carbines. Do you think they whined about them as much as we do with our AR-15s and reproduction 1911s with bells and whistles and a list of malfunctions that, if streamed from a printer and each owner got a chance to add his own complaint, and assuming the printer was a mesh of newspaper presses and an integrated instant-action notepad feature to instantly record these complaints, then maybe we could expect 1500 words per page, at a rate of 10 miles per minute.
A lot of complaints, my friend.
Here's your firearms related job. Fix the poor image by fixing the entire way you do business. This will create jobs that you want to do.
