    AR-15 Tools

    Using the right tool for the job is key to a successful build or repair. We understand that the average enthusiast does not have a budget for a drawer full of special or custom tooling. So our goal in this thread is to educate members, new and old, on the kinds of tools you may want to invest in or avoid while adding to your collection of armorer's tools.

    Make sure you subscribe to the thread. I will add tools via the edit button to keep the list in one location. You can click on the images for a larger view.

    First we'll show some special tools that are geared toward high volume repairs. All of them are one offs and cost a small fortune in time to manufacture.


    Flash Hider / Compensator Tool

    At two feet long and weighing in at 4 pounds, this special tool can double as a weapon. The three slots are .740, .745 and .750 inches. The spread allows us to choose the best fit when installing a compensator or flash hider and eliminating bite marks resulting from wrench flats that are to narrow.




    LaRue Barrel Nut Tool

    We are big fans of the LaRue Tactical Handguard. To expedite installation we manufactured another high speed tool. Traditional three pin tools are problematic because one of the pins acts as a pivot and prevents the third pin from completely engaging the nut. This leads to fractured or broken tools. Our has six precision pins made out out of tool steel and hardened to about Rockwell 50.






    Upper Receiver Vice Block

    Throw out the T-Handle that comes with it as it serves no purpose. The chances of you crushing a 7075T6 receiver before your vice explodes is improbable. The hinge on top is the first thing to go, literally. I mill it off because it will break anyway. It also makes it much easier to the receiver in and out with the hinge gone. The aluminum block obviously keeps the top half of the clam shell shut. I have at least 6 of the blocks modified for various operations.




    SAW Basic Armorers Tool Kit




    Buffer Block

    Modified V-Block used to facilitate removal and insertion of the buffer roll pin.

    So if I understand this correctly, the FSB Tool pictured above is used to hold the barrel correctly indexed with the upper receiver during the torquing of the barrel nut? Preventing FSB cant?

    You got it. We use a sighting jig to find "center" prior to tightening the barrel nut. Slight adjustment can made with the barrel nut tightened but before final torque value is applied. Clear as mud?

    Copy that, understood. Thank you!

    Sounds fairly similar to my procedure. No special FSB tool though, I simply place a large bronze drift in through the FSB, and have an assistant hold the FSB against the direction of torque.

    Do you plan on adding photos of your “Sighting Jig” to this thread?

    I’m very interested in seeing how you guys perform the alignment procedure!

    I'm thinking "yes," but if not, then I would also like to hear all about those marvelous and mysterious SAW reliability package modifications.

    LOL....I say no.

    You can’t come here, show off a few tools, then hold back the good stuff.

    A beginners question: Do you folks at Specialized Armament manufacture or sell a nice heavy duty AR15 armorer's wrench? The reviews on the ones that I've seen have not been that good and most of the remaining others have been sold out for a while. If not, can you direct me to a reliable source. Thanks.

    How fast do you need one?

    Multitasker Tools has one in the works. Not sure though when it goes into full production, but if heavy duty is what you are looking for, this wrench should fit the bill.

    LE6940 Barrel Nut Wrench

    Here is one tool not to buy. It is manufactured by Arrington Accuracy Works and at $60 a complete waste of money. It may be made of chrome moly but it is not heat treated and the tines had to be cleaned up to get it to fit the 6940 barrel nut. After 6 rifles it is a complete loss:
