Win. 670 243 trade for O/U 410

[hunt crazy in ca]

I have a Win. 670 in 243.
I put a aftermarket Pachmayr but pad on it as well as had a custom muzzle brake put on it (GS said he cerkoted the brake, apparently Hoppes 9 will eat it off). I did bed the rifle as well. Has a Bushnell Elite 3200 3-9 on it mounted in Leupold base/rings. I though it would work for my two little boys but i ended up just building them a 223. Now I need a shotgun for them...LOL!
Really just want to trade for a O/U 410 shotgun.
If I had to sell it. $500.00
