P90/PS90 Package

This package contains the URBAN-SENTRY single point/two point hybrid sling. It comes complete with the rear P90/PS90 Rear Harness Adapter and the upgraded P90/PS90 front Harness Adapter. This kit comes with everything that you see in the photo.  This revolutionary sling quickly converts from a TWO point sling to a SINGLE point sling by simply reconfiguring it.  This allows the operator to choose which configuration will suit them best for the right situation. The Single point sling configuration, or ONE Point, is more beneficial in urban areas in close quarters, whereas the two point configuration will work best in rural areas and at the range. The conversion can be completed in less than a minute.


  • The URBAN-E.R.T. URBAN-SENTRY Hybrid Sling is totally ambidextrous one point and two point sling.
  • The US2 features a 2" wide main sling body which affords the operator a lot more comfort over longer periods of carry. Unlike the 1" & 1-1/4" slings that tend to cut into your shoulder and neck.
  • The sling has an incorporated elastic Expander that only expands about 2.5" which helps with keeping the sling tight but allows for better movement without restriction.  It is under your offhand arm unlike bungee slings that bounce and can cause the weapon to smack you in the face.
  • The URBAN-SENTRY is made with 1" and 2" wide Military Spec Nylon MIL-W-55301 webbing.
  • The main sling body is universal to all weapons.
    • Made in USA
    • Unconditional Lifetime Warranty
    • Made with MILSPEC MIL-55301 Webbing
    • Made with IR Reducing ITW Military Products hardware
    • Modular One Point and Two Point design
    • 100% Ambidextrous


New and improved Front PS90 Harness Adapter that replaces the previous adapter shown in the PS90 Sling video demonstration below.

    Great P90 sling

    Posted by Matt on Oct 31 2016

    I love the 2 point configuration and that it is ambi, I'm left handed. I had a hard time figuring out how to set it up, luckily there was a you tube video, but detailed pictures and instructions would have made this better and easier. Quality and craftsmanship are great.

    Great sling!

    Posted by Stone on Aug 11 2016

    Installation is straight forward and easy. I'm use to rapid adjustment slings and contemplated buying just the mounting harnesses and using a sling I already had, so happy I didnt. The sling it self is sweet! If I had to critical, the only negative is some of the stich work had "tails" (short lose threads from where it was tied off and cut)... quick hit with a lighter, problem solved. The sling design makes toting the PS90 even easier. I'm not a one point sling fan, but having that option with just a few changes is a nice feature.

    Well made and well designed

    The sling was designed extremely well allowing the PS90 to be carried cross body and at the ready very comfortably. The sling is also well stitched and made with great quality and craftsmanship. The only thing I would change would to be to include some pictures with the manual provided so that you can see how to install it but the website does provide this information.

    Exactly what I needed.

    Excellent quality sling and easy to configure to either one point or two point mode. Quick shipping and arrived with all requested accessories. I just followed the video step by step and converted sling to one point mode properly the first time. Couldn't be happier with entire experience, including supporting an American made product which I believe is a great value.

    I searched and searched for a good solution for a sling on my PS90. So glad I found ERT slings. The sling fit perfectly and looks great!

    Sling is made of a very thick material. It was easy to install, and makes the rifle comfortable to carry

    A little frustrating

    Posted by 4324 on Jan 15 2016

    Price is good for quality of workmanship, easy to order and delivered in a decent amount of time (snail mail). Even though there is a video installation the first time is a little tricky if you aren't careful. I got my Velcro turned around a couple of times and put the butt stock piece through the slot backwards once but it was me, not the strap. Video is great.
