It’s hard to imagine a company with a more expansive portfolio of weapon cleaning solutions than OTIS Technology. The company is a global leader and its products permeate armed forces around the world. With this kind of resume, it’s easy to sit around and enjoy your success; not the case with OTIS. New for 2016 is their AR Vent Hole Scraper to clean the most inaccessible and therefore ignored area on your weapon, the vent hole.
The vent hole scraper is very easy to use, simply install it to the end of your charging handle, rotate it 90 degrees to lock it into position; then push your charging handle into the upper receiver as normal. The tool’s 4 prongs will scrape the vent hole removing carbon and dirt buildup. The AR Vent Hole Scraper is one of those tools that make you wonder why someone didn’t come up with it sooner. You’ll want to pick one one up to add to your cleaning kit or armorer’s tool kit. Check it out, you can pick one up for about $10 – a worthwhile addition to your kit.
