    Bolt Extraction Device

    Here at the Wile E Coyote Institute for Applied Aeronautics (and Gunsmiting) we occasionally find a tool we really like. Here is one such tool that not only belongs in your shop toolbox, but in your range kit, and that goes double if you’re a unit or department armorer (or a small department’s go-to gun guy), or an SF guy that has to run ranges for the Third World, or a range officer at a range open to the public (almost the same thing).

    We’ve all seen the stoppage you get when an overpressure round, or maybe a nasty chamber in an unlined barrel on a bargain-basement AR, solidly stuck. It’s like the thing brazed itself in there! It’s hard to get enough leverage on a charging handle to move the bolt carrier back and unlock that damn-near-welded bolt. If the carrier is fully forward, you can separate upper and lower and attack the carrier from underneath, but if it’s back just a few millimeters it’s hard to separate the upper and lower.

    You can get a similar problem with a double-feed, commonly caused by crummy or worn-out magazines. Your gun is out of action until you can reduce the stoppage.

    And then there’s the circumstance, when some schmo brings the seized rifle in to the shop after getting the case stuck and then letting it sit for three months in the salty sea breeze, hoping that time heals all wounds.

    The US Tool & Design Manual Bolt Extraction Device is simplicity itself: a lever with a yoke at one end that can be inserted through the magazine well and pry the bolt carrier back. That lets you open things up and get the gun back into action, or at least, troubleshoot the problem. Here’s an image showing how it works, with the upper absent for clarity:

    It’s available in three versions: compact 5.56mm and 7.62mm versions, and a double-ended dual-caliber variety. (Of course these will work with other calibers on the same platform, so order the 5.56 one for .300 BLK, for example; the critical sizes are the bolt and bolt carrier).

    The dual-ended one is perfect for the shop workbench, and we could see the other attached by a clip to the rails on one’s field rifle. It would give you a way to clear this kind of stoppage in combat.

    Here’s what they say about their tool, for which they’ve applied for a patent:
    The Manual Bolt Extraction Device (MBED) is designed to be used in the event of a malfunction where you need direct access to the bolt carrier group (BCG) and the leverage provided by the charging handle is insufficient. The MBED is effectively used to clear the most common stoppages such as a double feed where the second round is wedged above the BCG. The MBED can also be used to clear an over pressured round or any stoppage where the casing is stuck in the chamber and has seized function of the rifle.

    The MBED can be used to aide in any stoppage where direct access to the bolt carrier is needed. The AR-15/AR-10 platform does not allow for the user to have access to the bolt like the AK47, M1 Garand or M14 style rifles. The charging handle gives minimal leverage to the bolt carrier group and requires multiple tools and at least two individuals to clear these stoppages. The MBED is a single tool that a single individual can use to get the rifle back into working order in a short amount of time.

    This is simple and that’s what makes it brilliant. We’re ordering one for the bench and one for the range bag, at least until we can figure out the rail clip that we want to make. You can buy the MBED here: https://www.ustoolanddesign.com/prod...raction-device

    Useless if you have a fixed mag AR. Just one more reason not to own one.

          I like it. Not $45 worth of like it, but I like it.

          Mortar method has yet to fail me. I've successfully unstuck a few peoples' AR's at the range. Surprisingly, I've never had that problem with my middling-to-crappy AR.

          Having said that...

              You all sound like amateurs if you ain't seen this kind of jam yet. OK, in fairness, I hadn't either until my last MDTS class where I witnessed another shooter with the most stuck AR bolt of all time. Mortaring, hammering with a punch, etc. - nothing cleared this sucker. The amount of force and know how applied was no match for the jam. This tool would have been nice and probably would have fixed it.

                ^^^Yep.^^^

                When I took an MDTS class a couple of years ago, during the malf drills, one person's AR was stuck so bad, the shell casing had to be driven out from the muzzle end with a brass rod and a hammer.

                    I am a newb when it comes to a lot of this stuff, so sorry about that. I'm not well versed in AR jams....

                      Yeah, I've seen it happen a few times - and have seen how easily one can break a charging handle when all other armorer's tools don't work and you're using a mallet to unfuck a stuck bolt.

                        So how would one actually use this tool?

                              That seems like the kind of device that I need but will never remember to bring with me.
