Honna,
If it's a top eject model,you will have to get a side mount,like I did. The scope will be offset to the left of the rifle barrel.It looks different;and some folks do not like it. But if you have normal abilities it is no problem to find the sight quickly.
There are a number of mounts,available that do not require drilling/tapping.
The only one still made is the Williams,which,in my opinion,is the best one.
