Guy's,
I have this same scope and it is worth 2x the price.
I do not know tanaka, so I have nothing to gain. (is that Toro Tanaka?)
I have this scope on a FX Monsoon ($1400 gun), that tells you my "real" thoughts of the scope:)
Everything about it is nice-
1" tube
Mil Dot
50mm adjustable objective
The ONLY thing I would change is the weight. It is a bit heavy for a scope this size.
Now, don't let that scare you off, we are talking ounces, not pounds, LOL!! and I am very picky:)
If I had the extra $$$ I would pick it up "just to have".
Oh yeah- if it will stand up to a Kodiak or Patriot, it will stand up to ANYTHING!! RWS 34's, Gamo,s, BSA,s, etc are toys when it comes to air guns, compared to a Patriot (I would love to have one:) Maybe one day...
Good luck with the sale...
