Ruger OM Vaqureo 357 4 5/8 color case frame

I think my uncle just got took, went and traded his old model vaqureo in on an Ar 15. They gave him $200 for trade in value, it was in 95 -98% shape, I have been wanting to buy it for years! Oh well thats how it goes, I would have gave him 300 -350 easy.
Ar 15 is A DPMS for $450 with a Hawke red dot.
