Underlug staples are authentic,stronger, easier to install, and they remove less metal than dovetail lugs. Not suitable for thin walled barrels. Staples work well for keys, pins, or supporting a sling swivel.

Our UL-104-B staples are made for thin keys, up to about .090" thick. The .425" slot width allows expansion of the barrel when hot, to avoid pinching the barrel,changing point of impact. These may be used with our steel 3/32" barrel pin. Drill .110" (7/64").

Always leave more than .050" remaining wall thickness.

Recommended for fullstock longrifles, fullstock Hawken rifles, and light halfstocks using thin keys.

Made in the USA, of malleable steel, they are virtually unbreakable.

How deep should holes be drilled? Hold the lug with legs upward. Place the pin or key in the open staple. Measure the remaining leg length extending beyond the key. Your pin or key should smoothly glide through the slot, touching the bottom of the barrel and the inside of the staple or lug.
