Might be a cheaper option, plus my experience of chopping barrels on a rim fire sometimes they are choked, learnt the hard way. Length don’t worry me as I use an over barrel suppresser
Calibre: .17 HMR

Yes mine is 1/2x20 also

Do you know what contour it is? Need to make sure it will fit in my stock etc. I'll need to do some research to confirm they are compatible. But feel free to contact me as I could be interested. Thx
