Developments from Gear Head Works

IMG_5386

While at Bullpup 2015, I got to spent some time at the Gear head Works booth with Paul Reavis, the founder and current owner. Gear Head Works and Manticore are probably the most prolific and dedicated Tavor accessory parts makers out there. Midwest dabbles in all sorts of products other than Tavors, while Rat Worx’s contribution to the rifle is really only their 9mm suppressor, that was actually made in partnership with Manticore.

Of these two Tavor parts makers, both have outstanding qualities and attributes that can be seen in their products. However, for the sake of this post I’ll specifically talk about Paul and Gear Head Works. Paul Reavis doesn’t do Gear Head Works for a full time job, he does it because his passion is small arms and machining. He works in the automobile industry in Tennessee, but this is where his background in machining came from and what lends himself to being an excellent machinist and churning out the parts he has available. On that same note, this is why he can take his time in prototyping parts and designing them, his career doesn’t depend on when he gets parts out to the market.

Probably one of the longer awaited products for the Tavor is an aftermarket charging handle, either in the form of closing, or otherwise. This one folds very nicely and out of the way, yet can be readily switched up to charge the rifle. This isn’t available for sale yet.

In order to produce a .300 Black Out version of the Tavor, Paul designed and created this entire jig, built around an actual Tavor rifle barrel and action, in order to really see what needs to be tweaked and changed when it comes to the design of a .300 Black Out barrel.

The current .300 Black Out barrel that Paul is still working on. He is having issues with certain loads of .300 Black Out, and thus wants to do some more serious testing before he releases it the general public. Notice his other creations with the ejection port cover gas block, built in QD mount, upper rail, and handguard.

A close up of the QD mount/ modified forward assist. This part isn’t for sale as pictured, and thus is more of a prototype that probably isn’t going to come to market.

This Tavor has been making the rounds on Facebook  and is a Jabba the Hutt themed paint scheme. It actually isn’t owned by Paul but instead by a friend of his who wanted him to showcase it at the shoot.

A forward mount designed for the KSG shotgun, incorporating QD mounts, a semi flash suppressor, sling swivel, and the serrated edges are for non compliance tactics in use by prison guards.

It also protects the inner controls and mounts behind the muzzle.

This is more of a novelty item that Paul created more for himself than for actual retail sale. It is a suppressed .50 caliber bullpup rifle with a cartridge made by Paul. It’s a .50 caliber bullet in a smaller case with only about 200 grains behind it. He said he loves it.

    I hope he uses that thing only with the suppressor, or the muzzle blast will probably burn the scope .

  • BrandonAKsALot

    Ahem, I think you mean Boba Fett/Mandalorian theme on that Tavor…. Not Jabba. Jabba is the fat blobby mob boss.

    • TheNotoriousIUD

      Thank you.

    • Dracon1201

      Exactly *Facepalm*
      Tips to the writers;
      If you don’t know exactly what it is, don’t specify, or ask someone that does. It’s a big thing on this site.

      • BrandonAKsALot

        Bunch of normies around here. Although geek culture is now the cool mainstream thing, so maybe I’m a normie now? Existential crisis!

        • iksnilol

          It’s kinda depressing to see thick rimmed glasses be considered fashionable. Especially considering how much flak I got for simply having (non-nerdy) glasses.

        • Dracon1201

          Lol, welcome to the paradoxes of modern culture!

          • BrandonAKsALot

            No sir, I don’t like it.

        • MR

          Ah, you’re likely not a normie. The “cool people” and lemmings are just riffing on “the next big thing” for a while, you’ll be back out in the cold soon enough. Or maybe that’s just sour grapes from someone who’s not even “geek chic”.

          • BrandonAKsALot

            I can only hope. I get scared not being able to recognize my own kind. If any of my own kind ever left home and got off the internet that is.

    • I grew up without a TV. Should’ve fact checked.

      • BrandonAKsALot

        How dare you not recognize an obscure character reference to something from pop culture?!

        The man is just bounty hunting for Jabba Hutt to finance his Vette.

        • MR

          Ah, you guys and your Star Trek shenanigans.

          • BrandonAKsALot

            It’s pronounced Star Tracks starring Luke “Kirk-Picard” Vader and an archaeologist named Leonard McCoy “Frodo” Solo.

          • I know.

            *Wars

    • I know.

      You are correct…AND, yes…I shot first!

      • BrandonAKsALot

        We all know you shot Greedo first. Geeze stop talking about it. George Lucas was the only one trying to fool himself otherwise. Just show up at Skywalker ranch and pop him in the knee and then ask him who shot first.

  • TheNotoriousIUD

    I like that shotgun.

  • Giolli Joker

    I guess the last tound doesn’t have 200 grs of powder in it…

    • Brandon Davis

      It looks like .510 Whisper to me (.50BMG bullet in chopped .338LM case) and I load them subsonic with about 25gr of pistol powder.

      • Giolli Joker

        Yep, he probably meant 20 grs.

  • Vhyrus

    You know, in all my time owning and shooting my tavor, I cannot remember a single time I put the thing to my shoulder and said “You know, this is nice, but it would be sooo much better if I could fold down my charging handle.”

    • kregano

      I think it could be useful for storing your Tavor or keeping it from getting snagged on stuff, but that’s about it.

      It does look nice though.

    What is going on in the photo with the rail is that he has a program for a CNC that machines the rail out of bar stock, but has not done the finishing steps to remove the extra material. They will then likely set it up in a second custom made fixture and a separate program to remove the excess material, and by the time they perfect their program and set up process for the first program there will be much less left over material.

    Basically there is a collet that holds the bar stock (the 3″ did or so rod that can be seen as a remnant at either end). That collet can turn 360 degrees. Then you have an end mill at the top in the 12:00 position that does the machining to the bar stock. Basically its like an old bridgeport mill with an indexing head, but the indexing head is also run on the CNC controller. I attached a photo to make more sense.

    There are other variations to styles of machine and how they cut, and this only really only describes a 3 axis vertical mill with a 4th axis, so it may have been done a bit different, but you get the general idea.

  • Nick

    OMG! 300 AAC in a Tavor? That’s awesome! Can’t wait til it comes out. I’ve always wanted mine to shoot that instead of 5.56.

    Wonder if he’ll include some sort of adjustable gas block to insure proper cycling with both subsonic and supersonic.

    • kregano

      I wonder how you’d do an adjustable gas block on a Tavor, since some of the Tavor rail designs would block easy access from the top/front.

    • Anonymoose

      IWI is supposedly working on a 7.62×51 version also, but it will have to be a whole new platform. I would love to have one of those with an 18″ barrel when they do bring them out.

  • 360_AD

    300 Blackout. Not 300 Black Out. And on the KSG muzzle shroud/accessory mount: “It also protects the inner controls and mounts behind the muzzle.” Inner controls? What inner controls?

  • Benedict Tan

    The KSG muzzle device might help alleviate people losing fingers or hands like we’ve seen on here before.

    Hey guys. I wasn’t aware this article was out. I would like to address a couple of things. The forward assist is going to be available. I’ve revised the design slightly and making another prototype.

    The 50 caliber cartridge is similar to the 510 whisper but a different case. It does not hold 200gr powder. Maybe 40 tops. And I only shoot it suppressed. I just couldn’t take my cans to IL where this was.

    The rail in raw aluminum you see is from the first operation but it is nearly complete. It is done on a 4th axis rotary in a CNC mill. The small end actually gets cut off in the same setup but we pulled it before it did that.

    The folding charging handle came from guys up north emailing me to make them a larger handle for gloved hands and guys down south wanting a lower profile handle. This was the logical solution.

    I had a great time at the Bullpup Shoot 2015. I was able to meet a lot of great people with similar interest. I appreciate Miles stopping by and taking the time talking with me as well. Next year plan on coming out and get your hands on this stuff yourself!

    the machining is done on a multiple axis cnc lathe. used a 5 axis cnc back in my days in technical school
