K Rounds USA handmade gun belts are crafted from the highest quality materials available. Webbing is milled in the United States and is a Mil-Spec Nylon Webbing 4088 Type 7. Next, we use a USA Hot Forged Alloy Steel that had been heat treated to produce the adjustor. This adjustor is proof tested to 2500 lbs making it one of the toughest buckles you can purchase. Finally, our craftsmen sew 2 layers of 1.75” webbing using domestic thread to create the finished gun belt. This is truly one of the finest handmade webbing belts you can purchase.
