This is a simple and effective tool that the professional shooter will appreciate. Carry it rolled up, and 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. We offer two styles of this product: For the greatest compactness when rolled up, choose the non-padded A1SM. For comfort and insulated padding under the section of the mat which you’ll lay on, choose the A2SM. PVC backing makes it waterproof.
