Our UL-TC-2 lug is slotted for a tiny key. The slot measures only about .262" x .087". Enlarge this slot with a file, as necessary. Ideal for use with our 3/32" pin, the long slot allows the barrel expansion when hot. Formed steel, the flat base is about .590" wide, and the dovetail is .476" long. Use it on fullstock rifles.
