Quantico Tactical Thursday – The THenar by High Ready Tool

When most shooters grip the front of their rifles for CQB shooting, they “C-Clamp” their thumbs over top of their rails. This method allows the shooter to grip the rail by applying pressure with the palm and four fingers of their hand and adds pressure to the top of the rail with the muscles in the thumb.

Developed by a prior senior firearms instructor at a special operations unit, the Patent Pending THenar ® allows the shooter to improve their grip of the front of their weapon, while simultaneously indexing at a fixed point and bringing their long gun to bear with far more control than possible before.

The Thenar ® provides a hard-point located on the side of the rail which the shooter wraps their thumb over at the web. By gripping with the thumb over this nub, the user uses their Thenar Eminence, the strong muscle group in the palm at the base of the thumb. This design also allows the shooter to bring their support hand into position on the weapon in a completely repeatable position and dramatically increases grip on the weapon and control of the forend under recoil. While usable with vertical foregrips or a bare rail, the THenar® is optimized for use with the Magpul AFG. The THenar ® has been called “The missing half of the AFG”.
The exposed end of each version of the THenar ® is a QD sling swivel point, removing the sling attachment point from interference with the shooters grip on the weapon under stress. The ambidextrous Thenar® is available in Picatinny, Key-Mod, and M-Lok and is proudly made of aircraft grade aluminum just outside of MCB Quantico VA.

The THenar ® is available from Quantico Tactical in any of their six retail stores, via their website or for unit or agency purchase, via their GSA schedule or the Defense Logistics Agency TLS-SOE contract.

    ~$32 for all curious parties.

    Interesting. I’ve got an old MOE handguard with a Magpul VFG, and I’ve always just rested my thumb on the left-side rail with a rubber ladder cover on it to achieve something similar as an index point. This would be interesting to try out to see if it is an improvement over that.

    They need to work on better names for their products. Really? THenar? Like T-Hee-nar? Or is it thee-nar with a weird capital H? How are people supposed to recommend your product to other people if they don’t even know how to pronounce it?

    • James says:

      pronounced thee-nar, apparently.
      ADJECTIVE – relating to the rounded fleshy part of the hand at the base of the thumb (the ball of the thumb).
      NOUN – A badass accessory used to index the grip of your support hand for superior control, accuracy and consistency.

      However I feel like they made the noun up.

    Seems like a solution for a nonproblem.

  5. mark says:

    It’s a actually pretty clever, reminds me of the thumb rest/ “gas peddle” added to some Open Division pistols.

  6. Andrew says:

    Go Gun USA has had the Gas Pedal RS2 for a few years. Works well/best with an AFG. And if you prefer your sling mounted towards the rear of the rail instead of somewhere in the middle to middle front.

  7. John Smith says:

    I use a Surefire X300 mounted forward to accomplish this same principle….if I understand it correctly.

  8. PTMcCain says:

    It actually looks like something that would be quite useful, maybe.

  9. N says:

    This, plus a angled foregrip on your AR15 pistol? Almost as good as a actual foregrip haha.
    Interesting idea that will be very useful for a select few I’m sure.

  10. Rick Fecal says:

    They should change the name of the “C-Grip” to the tactical pole smoking grip, because that’s what it is, the vast majority of people who do it don’t even know why they do it other than they saw another tool doing it.
