AGD sight rail -
Originally made this as a longbow adapter for the ULE body. Works great for that but can also be used as a sight rail. The one shown is ~2.5" in length and a weaver rail is cut into the top. The weaver rail can be made any length desired. Standard is 2.5", Add $5 for every extra inch of weaver rail desired.
