Bare Essential Gunsmithing Tools

The great thing is that modern firearms are designed to be stripped/cleaned with minimal tools. Some don’t even require anything but your hands and the gun itself.

Brass Hammer & Plastic Mallet

Sometimes you want a little more force but not with something that could mar any of your finishes…

Start Roll Pin with Hammer
Start Roll Pin with Hammer

A brass hammer gives you the heft needed but doesn’t mar the normally much harder steel of a firearm. This hammer has interchangeable heads of brass, plastic, rubber, and even copper.

And I also keep a standard Rubber Mallet for some more forceful jobs.

Punches

Punches let you drive pins that hold together many types of guns. Again, we go with brass punches so they do not mar up the gun. We use and love the Starrett Brass Punch Set since they have longer punches than normal gunsmithing sets.

Wheeler Hammer & Punch Set

Or you can go with the combination hammer and punch sets from Wheeler which should be more than enough for introductory gunsmithing.

Hex / Allen Key Wrench Set

Tekton Long Hex Key Wrench Set

A lot of firearm screws utilize hex or Allen key patterns. To make it harder, there are metric and U.S. standards that roughly correlate to the origin of your gun. This long arm wrench set makes it easy for both standards.

I’ve probably bought half a dozen sets to place everywhere since they are never around when I need them!

Screwdrivers

Stanley All-in-One

And of course screwdrivers, you’ll need a sturdy multi-purpose one as well as a precision kit.

Threadlocker

Blue Threadlocker

Screws in a gun go through an immense amount of stress due to recoil and some will actually start backing out. That’s where threadlocker or Loctite (brand) comes in.

There are a couple of varieties but the two most used are blue (medium) which is great for vibration issues (such as handguard screws) and can be easily removed.

And red (high strength) ($6) which is when you want to lock something for almost forever (such as scope rings) since it requires heat to remove.

More Specialized Gunsmithing Tools

Torque Wrench

If you’re doing anything with precision involved like putting on optics…you’ll want a torque wrench combined with threadlocker.

Wheeler FAT Wrench

Torque wrenches make sure you’re in spec with the in-lb force and that all the screws have equal tension.

And the industry standard (and our go-to for years) is the Wheeler FAT Wrench.

It comes with useful bits that will do for most jobs…and it’s super easy to dial in the appropriate force.

The Works is truly the works and even has its own super nice torque wrench. Pricey but the best shooters out there (and most of the Pew Pew Tactical team) has one in their range bag.

Trigger Pull Gauge

Doing some trigger mods?

You’ll want to make sure you’re actually doing something instead of going by pure feel.

We have an in-depth guide to the Best Trigger Pull Gauges.

But the simplest one that will work for all but the most OCD is the Wheeler Trigger Pull Scale.

Gun Specific Gunsmithing Tools

There are tons of gun-specific tools, but here are the main ones that you’ll likely use for your Glock and AR-15.

This tool is actually really useful to get the pins in and out without marring the polymer frame, and also to disassemble magazines.

AR-15 Armorer’s Wrench

There’s a lot of versions of the AR-15 Armorer’s Wrench…so much so that we have our own dedicated article.

However our go-to is the Magpul Version.

There are versions on Amazon but we haven’t had the greatest of luck with them breaking little bits when torquing important AR-15 parts.

AR-15 Upper Receiver Vise

If you’re adding a barrel (or taking one off)…you’ll need a special vise to make sure you don’t warp the upper receiver.

The current one we use is the Obsidian Arms.

Application Specific Gunsmithing Tools

There are too many to list here but they all depend on your specific application. If you want to fit 1911 parts, you’ll need some files and a polishing compound. But if you’re just looking to drift your AK sight, you’ll need a special tool.

Check out our DIY Gunsmithing Tutorials where we cover all the steps and necessary tools.

    To all the aspiring gunsmiths, order the Brownell's catalog. It's the best 10 dollars you'll ever spend. Along with all the tools there's separate sections for ar's, 1911's, rifles, shotguns other pistols and revolvers.

    Echoing the other comment related to screwdrivers, I would really recommend a Torque Screwdriver. Gun smithing frequently requires precision work and over-torquing can ruin a receiver's threading.

    All the tools you talked about are good basic tolls with the exception of the Stanley All-in-one screwdrivers. Th correct screwdriver will need to be hollow ground to properly fit the head of a screw. If you don’t use a hollow ground you are going to damage the head no matter how hard you try.
