I had been wondering about a mount for my Springfield 84C rifle as well. I had seen some older ones that were made for the smaller diameter scopes (7/8") and didn't want to resort to an odd sized scope. I also thought about fabricating a mount too but I don't have a milling machine at my disposal. Must be nice
Well, I had purchased a Weaver 10 side mount for another gun and ended up not using the mount for that gun. I happened to put it on my 84C and it matched up to the receiver perfectly. The thread size on the screws that came with the mount were too small. I tried a couple screws that I had lying around and found out that the 10-32 IIRC fit it perfectly. I went out and purchased some socket head cap screws, the ones that accept a smaller 3/32 socket. I purchased these specifically because I had to trim the screw down so they would fit in the hole. Maybe you have access to the right screws but I did not and neither did the hardware store
. No problem, I chucked the screws in my drill and reduced the head size with a file. I filed them down to fit perfectly in the recessed holes of the mount. I did have to ream out the screw holes on the mount a tad to compensate for the larger diameter screws.
The mount fit great and was real secure. The Weaver side mount is used in conjunction with removable weaver side mount rings. I happened to have a weaver 1" high side mount rings in my parts bin so I used it to attach the scope.
The scope mounted centered over the receiver and the bolt operated normally and didn't hit the scope. The only problem was when I tried to take out the bolt from the receiver. It would hit on the scope. I suppose I could have just removed the scope rings when cleaning the gun since the rings are made to be removed but I didn't want to hassle with it. I took a dremel to the bolt handle where it hit the bolt. It took a little time to take off the needed amount but now it operates like it should and looks like it came from the factory that way.
Now some may scoff at altering the bolt handle of a gun that was made in the 40's but mine was purchased for $30 and has issues with chrome flaking, some rust and the stock has seen its better days.
I am impressed with the fit and finish. I often sit it in the corner of my room just to take a gander at it. I plan on taking it squirrel hunting later this year. Not bad for a $30 beat up gun. So if your receiver is tapped and your model number matches the following you may be able to use the same setup: Savage 4C, 4CD, 4D, 4E, Stevens and Springfield 84C, 84CD, 84D, 84,E, 56C.
