What to Look For in the Best Scope For 204 Ruger
When I’m setting up my 204 Ruger, I think about what the rifle is meant to do. This little cartridge is a laser beam—it’s flat-shooting, has minimal recoil, and is built for precision on varmints and predators at medium to long range. Because of that, the scope you choose needs to complement those strengths. It’s not like picking a scope for a big-game rifle that might need a super-forgiving eye box for a quick shot; this is about precision and clarity.
The first thing I always consider is magnification. For the 204 Ruger, I find a variable scope with a top end of at least 16x to 18x is incredibly useful. It lets you really zoom in on a prairie dog at 300 yards or more. A lower end around 4x or 6x is still handy for scanning fields and acquiring closer-moving targets. You’re going to be using the higher magnifications a lot, so don’t skimp here.
Next up is the objective lens size. This is a big part of the clarity equation, especially in low light. A 40mm, 44mm, or 50mm objective lens gathers a good amount of light, making your target stand out against a shadowy backdrop at dawn or dusk. Just remember, a larger objective might require higher rings to get a proper cheek weld.
The reticle is your direct link to making the shot. For the 204’s trajectory, a reticle with hash marks for holdovers is almost a necessity. Whether it’s a standard Mil-Dot or a more modern Christmas-tree style, these markings let you compensate for bullet drop without constantly fiddling with the turrets. Speaking of turrets, I prefer exposed target-style turrets. They are easy to adjust quickly, and most good ones are resettable to zero, which is perfect for the dial-and-shoot style of hunting this rifle excels at.
Finally, let’s talk about build quality. Your scope needs to be tough enough to handle the vibration of shooting and the bumps of being carried in the field. Look for scopes that are purged with nitrogen or argon gas to prevent internal fogging and are sealed against dust and moisture. A robust one-piece tube construction is a sign of a scope that’s built to last. Getting the right scope turns a great rifle into a truly effective system.
FAQ
What magnification range is best for a 204 Ruger?
I’ve found that a versatile magnification range is key. Something starting in the 4-6x range on the low end and going up to 16x, 18x, or even 20x on the high end is ideal. The low power is great for scanning and tracking moving coyotes, while the high power is essential for precisely placing a shot on a small ground squirrel at extended distances. The 204 Ruger is capable of remarkable accuracy, and higher magnification helps you take full advantage of that.
Is a 50mm objective lens too big for a 204 Ruger?
Not at all. While a 50mm objective lens might make the scope sit a bit higher on the rifle, the benefit is superior light gathering. This means a brighter sight picture during the critical low-light times of day when many predators are active. As long as you use matching high-quality rings to get a proper cheek weld, a 50mm objective can be a fantastic choice for the best scope for 204 Ruger, especially if you often find yourself shooting at dawn or dusk.
Do I need an adjustable objective or side focus?
For the kind of shooting you do with a 204, I would say yes, it’s a very valuable feature. An adjustable objective (AO) or side parallax focus allows you to correct for parallax error at specific distances. When you’re zoomed in at 18x on a target 350 yards away, eliminating parallax makes a noticeable difference in precision. It ensures the reticle is on the same focal plane as the target, removing a potential source of aiming error.
What type of reticle should I get?
I strongly recommend a reticle with some form of ballistic markings. A simple duplex reticle is fine for closer shots, but the 204 Ruger is a long-range specialist. A reticle with hash marks, like a Mil-Dot or a BDC (Bullet Drop Compensator) style, allows you to hold over for bullet drop without taking your eye off the target to adjust a turret. This speeds up your shooting on multiple targets and is incredibly practical in the field.
How important are the turret adjustments?
They are very important. For varmint and predator hunting, I prefer exposed, tactile turrets that are easy to grip and turn. You want crisp, audible clicks (usually 1/4 MOA per click) that are repeatable and reliable. Many modern scopes also feature a zero-stop mechanism, which allows you to quickly return to your zero setting after making elevation adjustments for longer shots. This is a feature I now consider essential.
