I have a like new ARMS #38 swan sleeve in the standard lenth. It has the low profile (newer) windage knob. I installed this on my rifle and it has sit in the safe ever since. It doesn't have a scratch on it. $100 shipped.
email me at firstname.lastname@example.org if you have any questions or if you would like pictures.
I wouldn't sell this but I just got a SIR and I need a #40 for it.
