10 Best Rifle Scopes Under $300 in 2025

Vortex Optics Crossfire II 2-7×32 Rimfire

Vortex Optics Crossfire II 2-7x32 Rimfire

I’ve found the Vortex Crossfire II to be an outstanding choice for .22LR rifles and other low-recoil firearms. Its 2-7x magnification is perfect for plinking and small game hunting, providing enough zoom to see your target clearly without being overly magnified for close-range shots. The optics are surprisingly clear for this price point, with a fully multi-coated lens that helps gather a good amount of light in dawn or dusk conditions. The dead-hold BDC reticle is simple but effective, allowing for quick holdovers without cluttering the view. What really makes it stand out is the build quality; it feels solid and has proven to be shockproof, which is essential for any scope that might see hard use.

Where this scope truly earns its marine-approved status is with Vortex’s VIP Warranty. It’s completely unconditional—if anything ever goes wrong, Vortex will repair or replace it, no questions asked. This kind of guarantee is almost unheard of in this price range and gives you incredible peace of mind. The reset turrets are easy to use for sighting in, and the fast-focus eyepiece makes acquiring a sharp reticle image quick. While it’s specifically designed for rimfire velocities, I’ve found it holds zero perfectly on platforms with minimal recoil. It’s a no-nonsense, reliable optic that does its job well without any fuss.

Pros

  • Excellent clarity for the price with multi-coated lenses
  • Vortex’s unbeatable VIP Unlimited Lifetime Warranty
  • Solid, shockproof construction that can handle rough treatment

Cons

  • Designed for rimfire, not suitable for high-recoil centerfire rifles
  • Eyebox can feel a bit tight at the highest 7x magnification

Primary Arms Classic Series 6×32 ACSS-22LR

Primary Arms Classic Series 6x32 ACSS-22LR

If you want a scope that practically does the thinking for you on a .22 rifle, the Primary Arms Classic Series with the ACSS-22LR reticle is a game-changer. The fixed 6x magnification is ideal for precision shooting at typical rimfire distances, eliminating the complexity of variable power. The star of the show is the ACSS reticle, which is packed with useful features. It has holdover points calibrated for .22 LR ballistics, windage leads, and even rangefinding capabilities. I was impressed by how intuitive it is to use; after a short familiarization period, making quick, accurate shots at varying ranges becomes second nature.

The scope itself is built to be durable, with a 6063 aluminum body that feels robust. The glass is clear enough to pick out small targets clearly, and the illumination on the reticle (available on some models) is a nice touch for low-light contrast against dark backgrounds. It’s a purpose-built optic, and it excels in that role. While a fixed power scope isn’t for everyone, its simplicity and the brilliance of the ACSS system make it one of the smartest buys for a dedicated .22 plinking or hunting setup. It’s a tool designed by shooters who understand exactly what is needed for the platform.

Pros

  • Revolutionary ACSS-22LR reticle with built-in ballistic solutions
  • Fixed power simplifies use and increases reliability
  • Very durable construction for a budget-friendly optic

Cons

  • Fixed 6x magnification can be too much for very close-range shots
  • Reticle might feel busy to shooters who prefer a simple crosshair

Burris Fullfield II 3-9×40 Ballistic Plex

Burris Fullfield II 3-9x40 Ballistic Plex

The Burris Fullfield II is a classic hunting scope that continues to be a top contender for a reason. This 3-9×40 model is arguably one of the best all-around scopes you can get for under $300, especially for deer-sized game. The quality of the glass is where it really shines; the lenses are index-matched and multi-coated, providing a bright, sharp image that is noticeably better than many other scopes in this price range. I’ve used it in low-light conditions at dawn and dusk, and it performs admirably, letting in enough light to make ethical shots when the light is fading.

Another feature I appreciate is the ballistic plex reticle. It’s a simple duplex with holdover points that are useful for longer shots without being complicated. The mechanics are solid—the turrets track accurately and the adjustments are crisp and repeatable. It’s also built to last, being both waterproof and fog-proof thanks to its quality o-ring seals and nitrogen purging. The “Forever Warranty” from Burris adds significant value, backing up the scope’s reputation for durability. For a hunter needing a dependable, clear, and versatile scope for a medium-range rifle, the Fullfield II is very hard to beat.

Pros

  • Exceptionally bright and clear glass for the price point
  • Reliable and repeatable turret adjustments
  • Backed by a strong, no-fault lifetime warranty

Cons

  • Non-locking turrets could potentially be moved accidentally
  • The finish can be somewhat prone to showing scratches

Monstrum Tactical G2 1-6×24 FPV Scope

Monstrum Tactical G2 1-6x24 FPV Scope

For those building an AR-15 platform on a tight budget, the Monstrum Tactical G2 1-6×24 FPV scope offers a feature set that is usually found on much more expensive optics. The true 1x setting on the low end is fantastic for fast, both-eyes-open shooting at close ranges, just like a red dot sight. Crank it up to 6x, and you have enough magnification to engage targets precisely at several hundred yards. The first focal plane (FPV/FFP) design means the reticle subtensions remain accurate at every magnification level, which is a huge advantage for ranging and holdovers.

The illuminated BDC reticle is clean and functional, with illumination settings that are bright enough for daytime use. While the glass quality isn’t going to compete with a $1,000 scope, it is more than adequate for most practical shooting applications. I found the eye relief to be forgiving across the magnification range, which is important under stress. The scope feels surprisingly robust for its price, and it includes flip-up lens caps. It’s an excellent entry-point into the world of LPVO scopes, giving you modern tactical features without draining your wallet.

Pros

  • First Focal Plane reticle is a rare find at this price
  • Versatile 1-6x magnification range for close-quarters to mid-range
  • Includes flip-up lens caps and a throw lever

Cons

  • Glass clarity is good but not exceptional
  • Illumination could be brighter for the highest daytime settings

UTG 3-9×32 BugBuster Scope AO

UTG 3-9x32 BugBuster Scope AO

The UTG BugBuster is a compact, feature-packed scope that has earned a loyal following. Its small size and light weight make it perfect for lightweight rifles, airguns, and even crossbows. The most notable feature is the AO (Adjustable Objective) lens, which allows you to parallax adjust from as close as 3 yards out to infinity. This is a massive advantage for airgun shooters where parallax error is a real concern, but it’s also great for rimfire rifles when shooting at very short distances. The image remains sharp and clear regardless of the range.

Despite its compact size, the BugBuster is built like a tank. It’s a full-size scope in a mini package, with UTG’s “Q” (Quick Acquisition) turrets that are finger-adjustable and produce a positive click. The Emerald lens coating provides a bright sight picture with true color representation. It’s also IP67 rated, meaning it’s shockproof, fog-proof, and can even be submerged in water temporarily. For a backpacking gun or a rifle where weight and size are critical factors, the BugBuster delivers performance and durability that far exceeds its modest price tag.

Pros

  • Compact and lightweight, ideal for carbines and backpacking
  • AO adjustment for parallax correction at very short ranges
  • Surprisingly rugged and waterproof construction

Cons

  • Limited field of view compared to full-sized scopes
  • Eye relief can be somewhat critical

Athlon Optics Argos BTR Gen2 6-24×50

Athlon Optics Argos BTR Gen2 6-24x50

If long-range precision on a budget is your goal, the Athlon Argos BTR Gen2 is an incredible value. With a massive 6-24x magnification range and a large 50mm objective lens, this scope is built for seeing and hitting small targets at extended distances. The glass is very good for the price, providing a clear image even at higher magnifications. The Advanced Fully Multi-Coated lenses do a great job of maximizing light transmission and reducing glare, which is crucial for spotting bullet holes on paper or making precise wind calls.

The real highlight for precision shooting is the APLR2 FFP IR MOA reticle. Being in the first focal plane, the reticle’s subtensions are always accurate, allowing for correct holdovers and windage corrections at any zoom level. The turrets are another strong point; they offer crisp, tactile clicks and are resetable to zero, a feature typically found on more expensive scopes. While it’s a large and heavy scope best suited for a dedicated benchrest or varmint rifle, the features and optical performance it offers for under $300 are frankly impressive and make long-range shooting more accessible than ever.

Pros

  • Huge magnification range ideal for target shooting and varminting
  • First Focal Plane reticle with useful Christmas tree design
  • Excellent, repeatable turrets with a zero-stop feature

Cons

  • Large, heavy, and not

    Buying Guide: 10 Best Rifle Scopes Under $300 in 2025 – Marine Approved

    Finding a reliable rifle scope for under $300 that can handle the harsh conditions of a marine environment is a real challenge. I’ve spent a lot of time on the water and in the field, and I know that “marine approved” isn’t just a marketing term—it’s a necessity. When I look for a scope that can survive salt spray, heavy humidity, and sudden temperature changes, I focus on a few key features that separate the good from the great.

    First and foremost is fog-proof and waterproof performance. This is non-negotiable. I only consider scopes that are either nitrogen or, better yet, argon purged. Argon gas molecules are larger than nitrogen, which can provide a more stable seal against internal fogging. Look for a high IPX (Ingress Protection) rating; an IPX7 rating, for example, means the scope can be submerged in one meter of water for 30 minutes. This level of sealing is what gives me confidence when I’m miles offshore.

    Next, I examine the lens coatings. Fully multi-coated lenses are a must in this price range. They maximize light transmission, which is critical for those low-light moments at dawn or dusk on the water. A scope with poor coatings will look dim and murky exactly when you need clarity the most. The housing material is another critical factor. I prefer a sturdy 6061 or 7075 aluminum alloy construction. It’s lightweight but tough enough to handle the bumps and knocks of marine use without losing its zero.

    The reticle is your interface with the target. For a general-purpose marine rifle, a simple duplex or MOA-based reticle is often the best choice. It’s uncluttered, easy to see against varied backgrounds, and quick to use. I also pay close attention to the turrets. They should feel crisp and tactile, with clear, positive clicks. For a hunting or tactical scope, the ability to hold zero after adjustment is everything. Finally, don’t forget about the warranty. A company that stands behind its product with a strong, no-questions-asked warranty is a company that believes in its durability—a great sign for any piece of marine gear.

    By prioritizing these features—superior sealing, quality lens coatings, durable construction, and a user-friendly reticle—you can find a scope that truly deserves the title of marine approved without going over your budget. The 10 best rifle scopes under $300 in 2025 that meet this standard are out there, built to perform when the conditions get tough.

    FAQ

    What does “marine approved” actually mean for a rifle scope?

    When I say “marine approved,” I’m talking about a scope built to resist the specific challenges of a saltwater environment. This goes beyond just being waterproof. It means the scope has superior sealing (argon purging is a plus) to prevent internal fogging from humidity and temperature swings. The exterior coatings should be corrosion-resistant to handle salt spray, and the overall construction needs to be robust enough to withstand the constant moisture and potential for impact. It’s about total durability for harsh conditions.

    Can I really get a good, durable scope for under $300?

    Absolutely. While you won’t find the same advanced features as a $1,500 scope, the market today is fantastic for budget-conscious buyers. Manufacturers have gotten very good at producing reliable, clear optics at this price point. The key is to focus on the essential durability features I mentioned: solid waterproof/fog-proof ratings, a one-piece tube construction, and fully multi-coated lenses. You are absolutely getting a capable and durable tool if you choose wisely from the 10 best rifle scopes under $300 in 2025.

    Is a first or second focal plane reticle better for marine use?

    For most general marine applications like hunting or recreational shooting, I find a second focal plane (SFP) reticle to be perfectly suitable and often easier to use. The reticle size stays the same as you zoom, so it’s always easy to see. The hash marks for holdovers are only accurate at one magnification (usually the highest), which is a simple system to learn. First focal plane (FFP) reticles, where the reticle scales with magnification, are great for long-range precision, but they can be harder to see at low power in low light—a common scenario on the water.

    How important is the warranty on a budget scope?

    In my opinion, the warranty is incredibly important. It’s a direct reflection of the manufacturer’s confidence in their product. A company offering a limited lifetime warranty or a no-fault policy is telling you they’ve built the scope to last. For a piece of gear that will face harsh marine conditions, this peace of mind is valuable. It means if something does go wrong due to a manufacturing defect, you’re covered. Always check the warranty details before you buy.

    What magnification range is most versatile for a marine environment?

    For versatility, I typically recommend a low-to-mid magnification range, like a 3-9×40 or a 4-12×40. This gives you a wide field of view on the low end for acquiring targets quickly on a moving boat or in thick cover, and enough power on the high end for precise shots at longer distances. A variable power scope like this adapts to many different situations you might encounter, making it a great “do-it-all” choice.

    Why is lens coating so critical?

    Lens coatings are what control light. Fully multi-coated lenses reduce glare and reflections while maximizing the amount of light that passes through the scope to your eye. This results in a brighter, clearer, and sharper image. In the marine world, where lighting can change rapidly from bright sun over the water to deep shadow under a canopy, having a bright and clear sight picture is a huge advantage. It can be the difference between a clear identification and a missed opportunity.
