This is a simple and effective tool that the professional shooter will appreciate. When it’s time to set up a shooting station, you simply hold the end and toss the mat out. With its weighted end, it unfurls and you’re ready to go. It’s long enough to cover the distance from below your knees to well in front of your barrel, so it is an effective muzzle blast dust suppression barrier. For comfort and insulated padding under the section of the mat which you’ll lay on, choose the Padded Magic Carpet Shooting Mat. PVC backing makes it waterproof.
