Review: Effective Product; Makes Live Easier - Very handy brush. Works well to loosen up all the chamber fouling so it can be cleaned out with a bore snake and an AR cleaning star. I just squirt some Zippo fluid on it, push it in, and rotate it a few times around (Zippo fluid is a decent solvent that evaporates without residue, so you don't have to work hard to then clean out the solvent you just used). The one thing to know is that it fits tightly in the chamber, so you can't just spin the cleaning rod with your fingers. If your cleaning rod has a fixed handle at the end that will work. If the handle spins, you'll need something to grip the cleaning rod so you have enough torque to rotate it. I clamp a pair of vise grips to the cleaning rod and then just rotate the vise grips. Works out great. I don't fault this product for that drawback, so much as the makers of most cleaning rods. ## Technical Specifications | Specification | Value | |---------------|-------| | Batteries Included | No | | Brand | OTIS | | Length | 10.75 Inches | | Width | 10.25 Inches | | Height | 1.5 Inches | | Weight | 0.85 Pounds | | Shape | Rectangular | | Number of Items | 1 | | Number of Pieces | 1 | ## Product Details - **Brand:** Otis Technology - **Included Components:** Otis Technology .223 Caliber/5.56 Chamber Brush - **Manufacturer:** Otis Technology - **UPC:** 014895003671 014895018842 - **Unit Count:** 1.0 Count ## Images ![Otis M-16 Chamber Brush - Image 1](https://m.media-amazon.com/images/I/51gvGy43uJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Five Stars *by D***E on 10 September 2014* You really need this to do a good cleaning... ### ⭐⭐⭐⭐⭐ Effective Product; Makes Live Easier *by Z***. on 13 November 2014* Very handy brush.

This brush cleans those very difficult nooks around the chamber very well. I have used this brush for around 200 passes through my AR now and it is still looking like new. I will note that you do need a rod, the Otis pull through system just does not have enough tensile strength to get this all the way into the chamber easily. So if you only have an Otis puck system be sure to build a rod into your cost (a short handgun rod works great). It is a specialty brush and it does cost a lot for what it is, but it works well and it seems like it is going to work for a long time as well. 5 Stars. ## Frequently Bought Together - Otis .223/5.56 Chamber Brush - Otis Technology 7.62 Chamber Brush --- ## 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.be/products/472446218-otis-m-16-chamber-brush](https://www.desertcart.be/products/472446218-otis-m-16-chamber-brush) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-06*
