Armorer's tools for AR-15


My idea of an essentials toolkit is one you can easily have with or at least real near you at any given moment. The reality, though, is that you can replace the military grade stuff that might fail with your fingers and a piece of brass. Trigger parts, bolt parts...and those are all small enough to carry spares of inside the butt stock or maybe the pistol grip...or in a fag bag on your hip.

I don't carry spare parts around with me but I do carry some tools.
 
I agree with the above for the most part, I believe your best bet is to go to Brownells and get something like the Real Avid master kit that comes with pretty much everything you would need.


Or you can peruse Brownells and get stuff piecemeal but the above kit would probably work just fine for the hobbyist and DIYer.
 
It's honestly best to just peace it together. I would start off with these, and don't cheap out on them.

Bench Vise

Standard Punch Set

Roll Pin Punch set and Roll pin starter punch.

Armors wrench and hammer.

JP universal vise clamp

AR15/AR10 Vise Block (Real Avid makes a decent one)

Gas Block assembly Jig

Ft- LBS Torque Wrench

In-Lbs Torque Wrench

Crowfoot Flare Nut Wrench Set

Reaction Rod for AR15/AR10

Bolt disassembly Tool.

Everything else you can pick up at your local hardware store.

That's what I'm trying to figure out, what companies sell the quality tools. I'm familiar with automotive work,and woodworking, so I know what the quality tools are and where to buy them, but building ARs is new to me so aside from general tools like, bit drivers, screwdrivers etc, I need to know who makes the best specialized tools.
 
Wheeler makes an entire "AR Armorers" kit for <$200 if I remember.

Top tier? Probably not.

"Essential" for when you need it? Probably.
PSA has that kit on sale for $79.99 (plus tax & shipping, as applicable) "today only".

No vested interest. Just happened to see it in an e-mail this morning.
 
Start with a good vice attached to a good bench/work surface.

I don't use any hammers or punches. But the action rods are a must have. Torque wrench is good to have with varrying barrel nut tools to suit what ever you are working on. I do barrel nut torque by feel now but if you want to make sure get a torque wrench.

Good Allen wrenches, a torch possibly, loctite red and blue, etc.

I just bought this thing which has that and more stuff built in. I haven't used it yet it's so new but seems decent.

you don't need that, don't waste your money
 
Which companies make the best quality armorer's/Gunsmithing tools to build AR-15s? I'm trying to put together an essentials tool kit.
Pretty hard to get all that you need from any one manufacturer .

Also depends on how for you want to go on the list of possibilities.

@MontanaMan nailed it. You won't be able to get all of the best tools from 1 company. For example, the best armorer's wrench I've used is my Magpul armorer's wrench. And either a Geissele Reaction Rod, or Real Avid reaction rod are a must-have. You will also need at least a good Wilton 4" bench vise. One tool I cannot recommend enough, is if you're building standard forged lowers, where you press in the trigger guard roll pin, get yourself a Wheeler Engineering Trigger Guard Install Tool. Don't try to hammer it in, you can break one of the flanges if you're not careful, or if you have the pin in crooked, or miss and hit the receiver. They are NOT very thick flanges.

You are right that tool is awesome and it comes in this set which has some great AR punches.
 
f you're only buying one I find the Midwest Industries reaction rod the most functional hands down. The "sail" on it helps prevent clocking of the barrel extension in the upper. It's also less expensive than the Geissele.
100% agree

I have most of the Wheeler punch sets and I’ll say the Avid Accupunch Master set is much nicer and all in one. Like a lot of the Avid stuff

I favor the design of MWI as well. Surprised KAC and Geissele did not incorporate the sail profile.
Geissele's and TechCo's receiver extension blocks are pretty handy as well. The extension on the TechCo allows the
lower to remain perfectly square with the receiver extension while tightening / torquing the castle nut.

For trigger guard installations you can use small hardware store brass plumbing fittings or Delrin drilled with a few relief holes which essentially are small bench blocks, Grade 8 bolt / nut being adjustable in height ; tape protect the brass before using. Need a proper sized roll pin holder starter punch as well. Receivers with coatings will almost always have reduced sized pin holes; chamfer the leading pin edge, use a little grease on the pin hole, cold blue the pin end after installation.

Sorry, I didn't link the set I was talking about above. Here it is with that trigger guard roll pin tool.


.
Geiselle makes a set of the gas bllck roll pint starter punches too, but w/o the hammer......................a must have if you many, makes life easy.

How do you install the bolt catch? How do you install the forward assist?
I still use a roll pin starter punch for the trigger guard, FA and bolt stop pins to get them started. But I press them the rest of the way with a 10" Knipex pliers wrench with some tape on the jaws. I've done it for gas tube pins as well.

If you 3d print..a lot of the jigs for pins, gas blocks, etc. can be made for cheap/free.

Tekton for the punches on my end, snagged their gunsmith set on clearance for 60% off, and they'll replace any broken ones for a lifetime.

the old tapco wrench is my favorite as far as armorer wrenches go..and midwest industries reaction rod.

As others have said, you'll likely be better off piecing together your set than buying a premade one.
 
Recently modified that above mentioned TechCo reaction block as it had no flexibility to adjust the width of various AR lower grip tang widths.
This new Arizona Ranger M4 lower was cerakoted, undoubtedly the root cause for being a few thousandths out of spec., but surprised the tool jig designer did not incorporate a simple method to accommodate tolerance variations. So, the jig grip tang element was 0.3775" of internal space; the M4 grip tang was .03880". Probably could have tapped into the jig at the expense of ruining the cerakote on the grip tang, albeit would never be seen by the judging public. Milled the jig to 0.050" width, the receiver extension jig will secure the lower perfectly square and with some polymer set screws to abut the grip tang for additional stability during use. Now the M4 at hand and for future projects this will not be an issue. Also an excuse to use my new set of Noga internal de-burring tools.

Musing on the lathe today. Fabricated a quick-reference guide gauge for AR carbine / rifle buffer spring lengths. I have observed some AR gunsmiths apply an adhesive measuring tape to the work bench, others take a yard stick for reference. Used 3/8" 6061 aluminum round stock to fabricate a 15" OAL gauge, creating precision Go-NoGo color coded zones for the two common spring lengths.
