A screwdriver set, a multi-tip driver, and bits is a good choice so that you can; tighten screws, and mounts, and disassemble and reassemble the firearm if necessary.

Multi-piece steel cleaning rod, in case you need to tap out a stuck case or a bullet from a squib round. (It has happened to me several times. A full-length coated steel rod is even better).
Masking tape. Gunsmithing tip: One way I use this is to determine how far back the bolt handle goes back on a semi if there is a consistent short cycle. Placed over the action, along the slot where the operating handle rides, when fired you can see how far back the operating handle tears the tape. That give you an indication and you can trouble shoot the problem from there.
Gun Oil and a good grease. Excessively “dry” guns that are tightly fitted will bind. A bit of grease or gun oil properly applied will do miracles. However, keep in mind oil and grease attract and collect grit and grime. LESS is often MORE….wipe off the excess and keep it out of the bedding of the stock.

Your digital camera or smartphone. Take pictures and videos to see what is happening with the gun when firing, or when something is broken you can show the customer a picture. Not just to post on social media (although I guess you can do that too….)
Magnifying glass, to look at firing pin indents, seeing cracks in metal parts, and many other uses. For example when a .22 Rimfire misfires, take a look at the indent in the rim of the case. How large is it? Is it the right shape? How deep is it? Does it look like it is providing enough disruptive energy?
Don’t forget a full set of Allen wrenches including those annoying super tiny ones that are used on many of the electronic sights these days.
Bore light and flashlight for seeing in those dark places.

Don’t forget hearing and eye protection! Protect what you have got!
Targets and a Stapler. Dang, I always forget those, and you don’t want to be that guy shooting at paper plates…. Just saying.
And now you need a great range bag to put everything in. I recommend this Side Armor Range Bag from Uncle Mikes which has space for everything you need and includes:
So start gathering what you need now before you head to the range. With these basic tools you will make the most of your time.
