Well, that is an interesting marketing strategy. Kinda puts a hazardous spin purchases for those who might want to collect these vice shoot 'em. So I reckon that my Golden Buffalo is more likely a Brass Bull, and as a collector or limited edition, not of any particular value other than the cost of a Buffalo Classic.
Fortunately I bought it because I liked the way it looked, not to collect. So any reservations I had about modifying a limited edition rifle by mounting a pseudo-tang sight are no more. Look out walnut... here comes the Dremel!
