Same as any pcp mostly leaks which is common for most rifles. I bough two at the same time about six years one .177 and .22 and only had a problem with the .177 which was a small leak from the Air gage easily fixed.

As I’ve said before have agood look over it take the stock of as well if it’s been played around with you will be able to tell easily enough if it has walk away. The wood on them is normally quit good check for any dents etc. As for a shoot of it if you have a chrono take it with you and do a couple of shot strings. If the seller tells you no sorry you can not try before you buy. Ask the seller if he has any paper work did he buy from new if so why take the barrel band off.

It’s the same as buying a car second hand at the end of the day go with your gut instinct. As to cost well its a buyers market at the moment especially with Daystates due to their new rifles coming on line.
Have you though about a Wolverine there are a fair few knocking about now again because of the new rifles cost out I love mine as I have four of them.

The only thing that I would be worried about is the lack of a barrel band but some owners leave them on and some off.

At the end of the day it’s your money not ours as I said gut instinct.

I may have one coming up for sale soon a nice limited addition called a Red Ranger dependant on how my divorce goes.
