What Size Scope Rings Do I Need For a 50mm Objective? Finding the Perfect Scope Ring
As a passionate rifle enthusiast, I’ve embarked on many hunting and shooting adventures, and the importance of having the right equipment cannot be overstated. One crucial aspect of ensuring a successful outing is properly mounting your optics, such as a rifle scope, on your firearm. Selecting the correct size of scope rings is paramount to achieving optimal eye relief and a secure mount. In this article, I’ll walk you through various tips and considerations for choosing scope rings that are ideal for a 50mm objective lens.
In short, for a 50mm objective lens, opt for 30mm scope rings if your scope features a 30mm tube diameter. While many scopes with 50mm objectives typically come with a 30mm tube diameter, it’s prudent to verify this information by referring to the manufacturer’s specifications for complete certainty.
Why Objective Lens Measurements Are Crucial?
The objective lens is the larger front lens on your scope. Its measurement, usually expressed in millimeters, represents the outer diameter of the lens itself. A 50mm objective is a very common size for variable power rifle scopes used for hunting and target shooting.
When fitting scope rings, you want them to be matched to the objective size so they fully support the diameter without blocking the lens. Rings that are too small will obstruct the edges of the objective. Going too big leaves less surface area holding the scope tight.
The size of scope rings you need for a 50mm objective will depend on the tube diameter of your scope. Most scopes with 50mm objectives have a tube diameter of 30mm, so you will need 30mm scope rings. However, it is always best to check the manufacturer’s specifications for your scope to confirm the tube diameter. You can also use a caliper to measure the tube diameter yourself.
Consider Ring Height
Standard ring height works for most rifle mounting situations. But you may need higher or lower rings based on your optics and the comb height on your gun stock. Higher rings lift the scope, allowing the proper head positioning behind it. Too low, and you’ll be scrunching down awkwardly.
Measure the distance from the top of the receiver to the comb on your cheekrest. Compare that to your scope length when estimating the ring height needed. Also, account for the thickness of any rail or base you’re attaching the rings to.
Go With Quality Brand Name Rings
Trusting cheaper off-brand scope rings is risky. Invest in established brands like Leupold, Burris, Warne, or Vortex that use strong metals and precise machining. The last thing you want is inadequate rings that loosen or fail in the field. Spending a few extra dollars gives peace of mind your optics will stay securely fastened.
Once you know the tube diameter of your scope, you can choose the appropriate size of scope rings. There are two main types of scope rings: single-piece rings and two-piece rings. Single-piece rings are more rigid and durable, but they can be more difficult to install. Two-piece rings are easier to install, but they may not be as rigid or durable.
Follow The Manufacturer’s Recommendations
Reputable scope and ring producers provide mounting guidelines and instructions specific to their products. Your best bet is to follow their advice for the appropriate ring size and position. They factor in objective size, tube diameter, recommended eye relief, and other specs when making recommendations. Do your homework and get it right the first time.
Key Takeaways
Here are some key takeaways on scope ring sizing –
- Match the ring diameter to your objective lens and tube size
- Account for factors like comb height and rail dimensions
- Quality rings are worth the extra cost for durability
- Follow manufacturer instructions for your specific optics
- Proper mounting equals better accuracy
With the right tools, you can be confident your optics are securely fastened for hunting seasons to come. Let me know if you have any other questions!
Frequently Asked Questions
- What if my scope objective is partly obstructed by the rings?
If you notice part of the objective lens is blocked, you likely have rings that are too small in diameter for that particular scope. Remove them and get larger rings that completely fit around the objective without blocking it.
- What mount should I use with the scope rings?
Most scope rings are designed to mate with standard Weaver or Picatinny rails. So choose a base or mount that has those fittings. Some rings may be proprietary to match a certain brand mount or receiver configuration. Again, follow manufacturer instructions.
- How tight should scope rings be?
Tighten the rings just enough to secure the scope without crushing it. Some recommend tightening until they are just snug, then add 1/4 to 1/2 turn more. Avoid over-tightening as that can damage the tube. The rifle’s recoil will further tighten the rings when fired.
- What torque setting should I use on ring screws?
Recommended torque varies by ring manufacturer and size. A common range is 15-25 inch-pounds of torque, but consult the guide that comes with your specific rings for proper specs. Use a torque wrench to prevent under or over-tightening the fasteners.
- How far forward should I position the scope in the rings?
Generally, scopes are mounted with the rear part of the rear ring aligned with the rifle’s ejection port. This puts the eye relief and zoom range in the optimal spot for most shooters. However personal preference may dictate positioning the scope forward or back to suit your needs.
End Note
With the right tools, you can be confident your optics are securely fastened for hunting seasons to come. Whether you’re a novice shooter or an experienced marksman, choosing the right scope rings and following these guidelines will ensure that your rifle and scope are optimally mounted, ultimately leading to improved accuracy and a successful shooting experience. If you have further questions or require assistance, feel free to reach out to experts in the field or consult with trusted manufacturers. Happy shooting!
