The ULoop is a clever and inexpensive solution to all sorts of sling-attachment and incompatibility issues. With a body of glass-reinforced nylon and a separate attachment loop of nylon-coated, stainless steel wire with crimped-on, ball shank ends, the device is both durable and non-marring. It can be installed through eyelets and through holes in railed handguards to replace hooks, clips and other conventional connectors. Attaching or detaching it takes only seconds and does not require tools. The ULoop is made in the United States and is available for 1"- and 1.25"-wide slings. Price: $12.
