I was able to purchase the sight for $300. I knew that price was a “bargain “ so I snatched her up ASAP. I’m going to install this on my 1905 carbine. It looks like I will need to do a little wood work in the front of the bolt release. I also think that the bolt stop will need to be worked on as well. It currently doesn’t release enough to allow the bolt to be inserted. Any input or suggestions would be appreciated.
