1. Trinity 4×32 Hunting Scope for Savage Model 64 FXP – Dovetail Mounted Mil-Dot Optic with Rings Matte Black
This budget optic earned its spot through pure affordability, offering shooters a complete setup right out of the box without breaking the bank. You get rings and a dovetail mount included, making it an accessible entry point for casual plinking.
I would rank this low on a serious precision list, but it works fine for basic rimfire duties. The matte black finish looks decent, though I suspect glass clarity will leave demanding shooters wanting more.
Buyers note that this scope provides an easy all-in-one solution for casual rimfire owners.
Reviewers appreciate the inclusion of mounting rings for the factory dovetail.
Some users caution that the optical quality struggles in low-light conditions.

2. MDT Field Stock Rifle Chassis System Compatible with Savage SA RH, OD Green
This premium upgrade belongs in the hands of dedicated marksmen who demand ergonomic precision from their rimfire builds. You get an adjustable length of pull and a properly shaped grip that completely changes how the rifle feels in your shoulder.
I consider this the absolute pinnacle of current Savage rimfire modification. The stiff aluminum backbone eliminates stock flex and elevates your accuracy potential overnight.
Shooters frequently praise the massive improvement in overall rigidity compared to factory plastic stocks.
Buyers highlight the comfortable vertical grip angle for sustained target practice.
Reviewers note that installation requires a compatible short action rather than a standard Model 64 receiver.

3. MDT Field Stock Rifle Chassis System Compatible with Savage MKII
An integrated aluminum skeleton hides beneath the traditional polymer exterior, which caught my attention as a brilliant way to blend classic style with modern rigidity. You get the benefits of a precision chassis without the ultra-tactical appearance that turns some shooters away.
I find this design fascinating for rimfire target builds because it bridges the gap between old-school aesthetics and modern free-float performance. You will appreciate the enhanced barrel clearance that keeps your shots consistent string after string.
Users report a noticeable boost in shot-to-shot consistency after dropping their action into this stock.
Buyers appreciate the clean integration of sling swivel studs for field carry.
Reviewers point out that this specific version is tailored strictly for the Savage MKII platform.

4. M1SURPLUS Optic Mounting Kit for the Rossi .22 Gallery Gun RS22 Savage Model 64 Rifles – Includes Medium Height Scope Rings and Dovetail to Picatinny Adapter Mount Base
The most common complaint leveled against this kit involves the bulk of adding a second adapter layer to your receiver, but the balanced picture reveals incredible versatility. You gain the freedom to swap out rings and transition from dovetail to a Picatinny rail with minimal hassle.
I view this hardware as a practical bridge for optics, even if it sits a bit higher than I prefer. You get plenty of mounting flexibility for whatever spare scope you happen to have lying around the workbench.
Shooters mention that the adapter provides a secure hold on factory dovetail rails.
Buyers like having the freedom to use standard medium height rings for various scope objectives.
Reviewers warn that the added height can sometimes create an awkward cheek weld on factory stocks.

5. Hilljak Savage 62 64 954 22LR Ergonomic Magazine Speed Loader, Quickie Loader (Neon Green)
Moving past the mounting kits and chassis systems, this bright loader tackles a completely different bottleneck by focusing on fast range reloading. You get a 3D-printed ergonomic body that saves your thumbs from raw friction during high-volume rimfire sessions.
I would pick this neon version over standard gear simply because it is nearly impossible to lose in the grass. You get a reliable thumb press that speeds up magazine loading without any complicated moving parts.
Users love how quickly they can fill magazines during extended range sessions.
Buyers note that the bright color prevents the loader from getting lost in the dirt.
Reviewers mention that it takes a short practice period to master the pushing motion.

6. Hilljak Savage 62 64 954 22LR Ergonomic Magazine Speed Loader, Quickie Loader (Hunter Green)
This loader built its strong reputation on simple durability, and my assessment is that the praise is mostly well-deserved for a molded plastic accessory. You get the exact same ergonomic thumb-saving geometry as its neon sibling, just rendered in a more subdued woodland tone.
I prefer gear that blends in, making this darker shade my personal favorite of the two Hilljak options. You secure a discreet range accessory that handles high-volume .22 LR reloading without drawing unwanted attention.
Shooters report that the material holds up well to repeated downward pressure.
Buyers appreciate the subtle color choice for low-profile range bags.
Reviewers confirm it functions identically to the brighter model while offering a cleaner aesthetic.

Choosing Between Them
The MDT Field Stock claims the top spot for completely transforming your rimfire rifle into a proper precision platform, though you should remember that this chassis requires a compatible Savage short action rather than the standard Model 64 receiver. For the ultimate setup, I recommend investing in the MDT Field Stock for serious accuracy, while budget-conscious plinkters will lean toward the Trinity scope or the Hilljak loaders for range convenience.
You should carefully match your purchase to your specific rifle model, as compatibility varies wildly between the standard Model 64, the MKII, and various aftermarket chassis footprints. By pairing the right ergonomic upgrades with your exact shooting discipline, you can turn an ordinary factory rifle into a true precision instrument.
