I don't know what a "Weaver Last edition K2.5" is exactly...but...I've got a nice steel-tube Weaver K2.5-1 with a duplex reticle which is marked "USA" and "Micro-Trac".
If that will fit your needs, $75 will get it to your door.
Thanks, thats still an older model than what I’m looking for. The last weaver k2.5 before they discontinued was aluminum, built in asia, gloss black, with current green weaver logo.
