This sight is designed for rimfire, AR-15 rifles, and pistol calibers. While it will hold up to the recoil of a 12ga in terms of durability, it would most likely lose zero over time and would periodically need to be sighted in again.
The Leapers UTG 3.8in ITA Red/Green Dot Sight w/ Integral Mount mounts to picatinny rail. If your Savage 64 has a picatinny rail scope base then the Leapers UTG 3.8in ITA Red/Green Dot Sight can mount to it. If your Savage 64 has grooved receiver for a dovetail mount the Leapers UTG 3.8in ITA Red/Green Dot Sight w/ Integral Mount will not be compatible.
As long as you have a standard picatinny/1913 rail, you can mount the Leapers UTG 3.8in ITA Red/Green Dot Sight. If you do not have a picatinny rail, you would need to use a Pic Rail adaptor to mount the optic.
