## Description

NSN: 8470-01-599-3851 Size: Fits Small through X-Large helmets Developed by Ops-Core, the ECH/ACH Improved Retention System (IRS) is a complete assembly in OCP Tan 499 to retrofit for ACH, ECH, MICH or Ops-Core helmets. This is standard equipment on the new Enhanced Combat Helmet that is replacing the current ACH, or a great upgrade to your current helmet. The system is adjustable for one-size-fits-all design. The straps are adjustable using ladderlock buckles that insure a snug fit to the chin and helmet. The attaching hardware (included) consists of four black ballistic steel screws and t-nuts that secure the IRS to the helmet.

Nape pad provides optimal comfort for a snug and secure fit.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great improvement from old ACH
  

*by Z***K on Reviewed in the United States on February 3, 2023*

If you're looking for a replacement for the old ACH retention system this is a great option. It's very comfortable and easy to install. You can quickly adjust the straps with ease, no more taking the helmet on and off to get the perfect fit. Leather backing on the chinstrap makes it very pleasant to wear. I would definitely recommend the over other ach retention systems.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Comfortable. Easy to install.
  

*by J***. on Reviewed in the United States on April 30, 2022*

I bought this strap as a replacement for my 2007 MSA ACH strap, which was super old and was missing parts. Strap is nice and comfortable and easy to install. The only problem I had was removing the screws that were factory on my helmet. The steel was too soft, however the hardware this strap comes with is stronger and I didn't have any problems correcting it.ONE SIZE FITS ALL.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Pretty good.
  

*by G***E on Reviewed in the United States on March 9, 2021*

Overall satisfied. Pretty easy to screw in even with just a gerber. Fits well on a regular ACH or high speed helmet I’m assuming. Definitely more comfy with that leather or hide on the chin strap. Will get ugly and oily in the future I’m sure but for now it’s a solid buy.
