Well I guess I misjudged the knowledge on this forum! Oh well! BYE!

I sold an SSK rechambered .411 JDJ 12" barrel, cut and recrowned, chromed, and magnaported with dies and 4 boxes of Barnes .411 X bullets (about $45 a box retail), as well as several other boxes of cast and jacketed .41 cal pistol bullets for $450 plus shipping (it was approx. $850 worth of equip and gunsmithing, if that gives you an idea).
I can't really ay about the scopes.
A 10" blue .223 barrel would be worth around $135 to $150 bare on E-bay, which is where your friend would probably get the best price in the shortest amount of time.
If he wants to sell them, E-bay would be the best advice I can give.
