You may save money buying second hand but why are they for sale?
There's not much out there on the vari mag front, if you don't want to spend upwards of 3k.
I won't buy another mk3 nikko due to bad experience and the Sightron I had just didn't do it for me .
So what else is there that's light ,variable mag and under a grand?
About as much use at field target , as a life guard at the Olympic swimming pool.
