Arken Optics SH4 GEN2 4-16X50 Rifle Scope FFP
This is the scope I consistently recommend for serious rimfire shooters who want precision tracking without breaking the bank. Mounted on my Cooper 38 in .22 LR using a 30mm one-piece mount, it delivered excellent repeatability.
Product Specs:
- Magnification: 4-16x

- Turrets: 0.1 MIL
Pros:

Glass clarity is surprisingly sharp for this price range. Edge clarity holds up well, and chromatic aberration is minimal even in high-contrast lighting.
Eye relief is forgiving at around 3.5 inches, and the eye box remains usable even at 16x. That’s important for quick target acquisition.
Durability is outstanding. I ran over 400 rounds and confirmed zero retention. The scope handled mild rain and temperature shifts without fogging.
Turrets are tactile with clear clicks. I ran a box test and tracking was consistent—rare at this price point.
Magnification range is ideal for 50–200 yards. Parallax adjustment works smoothly down to close distances, which is critical for rimfire.
Mounting was straightforward with standard 30mm rings. Clearance was good even with a heavy barrel.
From my experience, this scope feels like a precision tool. Reddit users often praise its tracking reliability and value.
Verdict: Best balance of performance and price for precision rimfire.

How to Choose the Right Scope for This Pistol
Selecting the right optic for a Cooper Model 38 requires understanding how this rifle is typically used. Most shooters use it for precision rimfire shooting between 25 and 200 yards, so your scope must match that performance window.
First, magnification matters. I recommend 3-9x for hunting and 4-16x or higher for target shooting. Too much magnification can make the rifle feel unbalanced, especially since the Cooper 38 is lightweight.
Second, consider focal plane. First focal plane (FFP) scopes are better if you plan to use holdovers or dial adjustments at different magnifications. However, second focal plane (SFP) scopes are simpler and ideal for hunting.
Third, pay attention to parallax adjustment. Rimfire shooting often happens at shorter distances, so a scope with adjustable parallax down to 25 yards is a huge advantage.
Weight is another factor. Heavy scopes can throw off the balance of the Cooper 38, which is known for its elegant handling.
Turret quality is critical if you dial frequently. Look for consistent tracking and tactile clicks.
Finally, glass quality should not be overlooked. Clear optics help you spot impacts and improve accuracy, especially in low light.
