This bag is designed to carry/store machine gun barrels, but you can use it to carry SBRs, uppers, etc.
According to Bulldog:
•The exterior of the bag is 100% water and wear-resistant
•The interior of the bag is heat-resistant to 1800 Degrees
•The interior of the bag and thread is 5 X stronger than steel
•The thermal barrier protects the soldier from the hot barrel
•A hot barrel can be placed anywhere on the interior of the bag
•The shoulder strap has 3 inch wide 20 inch long closed cell pad inside
•The zippers are impervious to corrosion and are unaffected by heat and cold
•Two exterior pockets are designed to carry cleaning equipment and spare parts
This bag is new and in great shape. Asking $100 shipped, or best offer. These aren't my pictures, but that's what is for sale.
BUMP - price lowered. I'll entertain reasonable offers.
