0-09 P90/PS90 REAR HARNESS ADAPTER The P90/PS90 Harness Adapter is made of heavy duty thinner Mil-Spec W-55301 webbing, 1” male & female ITW Ghillitex side release buckles, and hook & loop Velcro. The P90/PS90 Rear Harness Adapter attaches to the rear of the stock utilizing the P90/PS90’s existing rear sling attachment, and the thumbhole to help stabilize the harness to the weapon. The P90/PS90 single point and two point sling attachment point is at a position that aids in keeping the weapon at a better center of gravity, thus keeping the weapon at a higher point on your torso. The P90/PS90 Rear Harness is 100% ambidextrous, and also allows the weapon to hang vertically thus preventing the weapon from hanging at an angle as the weapon’s existing sling attachment point does.

  • Made in USA
  • Lifetime Warranty
  • Made with MILSPEC MIL-55301 Webbing
  • Made with IR Reducing ITW Military Products hardware
  • Modular single point and two point design
  • 100% Ambidextrous

    Perfect fit

    This was one of the adapters I needed to use for my PS90 to work with the sling I already have. Now I can attach my sling to my PS90. I love the Urban ERT slings as with the proper adapters you can configure for different firearms without having to purchase separate slings for each model. Get the adapters and you are all set. High quality materials and come in ATACS-AU to match my sling.

    Awesome piece of kit

    It seems like the P90 was designed around this harness instead of the harness being designed to fit the firearm. This is a time proven, very high quality harness. Highly recommend.

    I was skeptical at the price, product is excellent

    When i saw the low price point i was extremely skeptical, but i figured it was low enough to take a chance.
    I received the sling adapter in record time, so major props to the shipping department.
    I was impressed with the quality of the sling adapter, i watched the video above before i ordered so i was ready to install it as soon as i opened the package. The adapter didnt even need any adjustments, it fit like a glove as soon as i snapped it all together.
    This sling adapter gave me exactly what i was looking for, an extremely solid platform to mount a single point sling. I went ahead and ordered one of the little extenders too so i can use it with a wolf hook.
    I ordered the black adapter (because ive had issues with receiving the wrong color than ordered from other companies, these guys get props for getting that right as well) so i cannot vouch for the patterns, but the ones in the pictures look pretty sick. Mine is a true black though, so i am very happy.
    If you have a p90/ps90 and you dont want to mount those QD nuts to the body (I didnt, i hate the QD nuts that came with my carbine) this adapter is the best ive seen.
    I will definitely be ordering from these guys the next time i need a sling. A very reasonable price and an incredible product with very fast shipping and quality control.
    These guys rock.
