Funny you should ask about this! I have an Eberlestock
scabbard that I bought new about 5 years ago for my Sendero with NF 5.5-22X56, but never used. I was just thinking that I should list it in the classifieds for someone who could use it. They cover the gun well and with all of the strapping on them, there are a lot of ways to attach it to your frame. If you added one of the buttstock covers, it would be nearly 100% covered. Not trying to sell it to you, but I believe something like this would work well for your purpose and if you are interested, PM me. Have a great day.
