Harris Bipod clamp-on leg adapters

Primary Adaptive System Solutions has an interesting solution for users of Harris bipods.

The product is called “Primary Adaptive System Solutions (P.A.S.S.) Harris Bipod clamp-on leg adapters“.

It’s a small CNC machined clamp-on adapter, when mounted to your Harris bipod leg allows you to mount an additional set of bipod legs.


Yes, it might make your rifle look like is has an antenna attached however in practical shooting or 3 Gun there’s sometimes a need to go from short legs to longer legs on your bipod, or vice versa.

For instance you would like to shoot a stage from a kneeling position, with long bipod legs, then go prone with short legs.


You could have several bipods attached, with quick detach,  a solution I’ve used it to nail various stages.

Or you could use one bipod, and have the clamp-on attached with the possibility to change the length of the legs.

There are discussions within the IPSC Rifle Rules to ban this kind of usage of multi-bipods. Probably as it looks a bit silly, and isn’t considered to be practical. However, the solution pictured would most likely still be legal with the rules. Technically it’s just one bipod, but with more legs.


Just beware so you don’t sweep your hand or fingers in front of the muzzle.


Below, a solution with B&T Industries Atlas Bipod Spike Feet fitted.


Here’s a short demonstration video of the function. I’ve seen them being used by a friend (bipod master level 10),  and I’d love to try this system out.

The price is $ 64.95 and you can find them here:

    If it’s stupid, but it works, it’s not stupid.

    Why stop at two sets of legs? Spider rifle? Centipede?

    • Anonymoose

      What about a machinegun on a tripod with the bipod down too?

      • Phillip Cooper

        Mind. Blown.

      It could do double duty as a microwave antenna array. Just be SURE to clear the chamber!

    One bipod with four legs? Methinks that’s not a bipod! Quadripod?

    It looks really stupid, but I could see some utility in this.

  • yodamiles

    Does it works as emergency bayonet?

    I just finished my AR-10 build and I would like a bipod and this doesn’t look too bad.

  • Anonymoose

    Yo, dog, I heard you like bipods…

    spider-pod, does whatever a spider-pod does.

    Can’t you just use sticks? I’d think they would be faster than this kneeling or standing. I can shoot almost as well as prone standing with a good 3 stick set up, but 2 would be faster and good enough for competition I’d think..

  • mechamaster

    They should try experimenting with telescopic “tripod” design…

    The user can utilized the extra 1 leg ( mainly the middle ) as the forward-grip..
    or only deploy the left-side / right-side leg as the angled grip / support againts the wall..
    or deploy the tripod / bipod mode in prone / sitting position.

    Wouldn’t that be a quadpod?
