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. Unlike the old screws, these lock only require one-hand to tighten and won't backout. The IRS features a leather chin-cup and H-Nape pad for comfort. Nape pad provides optimal comfort for a snug and secure fit. Review: Comfortable. Easy to install. - 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. Review: Perfect upgrade to your ACH! - This honestly changed everything. I used to get really bad rash where the old issues straps were and whenever I would shoot with nods the whole ACH would run down no matter how I tightened. This thing fixed both issues and make adjustments way more comfortable and secure. I would buy again in a heart beat! Definitely worth every penny! ## Features - Helmet is 3X more stable under rotational forces - Sliders allow one handed on the fly adjustments - Unique geometry & design eliminates loose ends - Padded leather chin cup and nape strap for comfort - Comes with universal mounting hardware ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CKWGBYY | | Age Range Description | Adult | | Best Sellers Rank | #294,840 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #371 in Women's Military Clothing #623 in Protective Body Equipment #1,488 in Men's Military Accessories | | Brand Name | Government Contractor | | Care instructions | Spot clean with a damp cloth.

Easy to install. *by J***. 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.

ONE SIZE FITS ALL. ### ⭐⭐⭐⭐⭐ Perfect upgrade to your ACH! *by K***T on May 30, 2019* This honestly changed everything. I used to get really bad rash where the old issues straps were and whenever I would shoot with nods the whole ACH would run down no matter how I tightened. This thing fixed both issues and make adjustments way more comfortable and secure. I would buy again in a heart beat! Definitely worth every penny! ### ⭐⭐⭐⭐ Pretty good. *by G***E 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/76349075-usgi-ach-irs-improved-retention-system-h-nape-helmet-chin](https://www.desertcart.pt/products/76349075-usgi-ach-irs-improved-retention-system-h-nape-helmet-chin) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-01*
