WTT Low Picatinny 1" rings for 30mm

[ianpadron]

Got these with a rifle purchase, brand new never been out of the package. I've seen them retail between 130 and 180 bucks

Would like to trade for a similar set of high end rings, but in 30mm. Low height only. Don't need to be new but excellent condition preferred, brand doesn't matter.

Thanks!
