How To Properly Lap Scope Rings?

There are a few things you need to take into account when lapping scope rings. The first is the type of ring you have. There are two main types of rings: split and solid.

Each has their own advantages and disadvantages. The second thing you need to consider is the height of the rings. This will determine how much clearance you have between the bottom of the ring and the top of the scope tube.

You also need to think about what kind of tools you will use for lapping. The third, and final, consideration is your budget. Lapping tools can be expensive, so if you’re on a tight budget, you may want to consider hiring someone to do it for you.

With that said, let’s get started!

  • Choose the right size lapping tool for your scope rings
  • The two most common sizes are 1″ and 30 mm
  • Place the ring on the lapping tool so that the inside (bore) of the ring is facing up
  • Apply a small amount of lapping compound to the outside (bottom) of the ring
  • Use a slow, circular motion to lap the ring until it is smooth and even all around
  • Remove the ring from the lapping tool and clean off any excess compound with a cloth or brush

How Far Apart Should My Scope Rings Be?

There is no definitive answer to this question as it depends on a number of factors, such as the type and size of scope, the caliber of rifle, and the shooting application. However, there are some general guidelines that can be followed when determining how far apart to place scope rings. For most scopes, it is recommended that the rings be spaced at least 3 inches apart.

This ensures that there is enough clearance for the eyepiece and allows for proper eye relief. If using a larger scope or one with a longer eye relief, 4-inch spacing may be necessary. When mounting a scope on a rifle, it is important to make sure that the rings are aligned properly.

This means that the front ring should be centered over the barrel and the rear ring should be centered over the receiver. Failing to do this can result in poor accuracy and grouping. Ultimately, the best way to determine how far apart to place your scope rings is by trial and error.

By experimentally mounting different scopes on your rifle and shooting at various distances, you will quickly learn what works best for you and your equipment.

What is the Purpose of Lapping Scope Rings?

Lapping is the process of using abrasive materials to wear down metal surfaces in order to create a smooth, level surface. When lapping scope rings, the goal is to create a perfectly flat surface on top of the rings so that the scope can sit evenly and securely in place. This process is important because even the slightest unevenness in the surface of the rings can cause problems with how the scope sits and performs.

Lapping scope rings is not a difficult process, but it does require some time and patience. First, you’ll need to gather all of your materials. You’ll need two pieces of lapping film (coarser and finer grit), lubricant, ring clamps, and something to prop up your work area (a vise or stable table).

Once you have everything gathered, you’re ready to begin. Start by attaching the ring clamps to your scope rings. Then, apply a generous amount of lubricant to both sides of each piece of lapping film.

Next, sandwich thescope ring between the two pieces of lapping film (lubricant side down) and clamp everything together tightly. Now it’s time to start moving! Gently movethe entire assembly back-and-forth across your work surface for several minutes (longer if needed).

As you do this, you should see the abrasive material slowly wearing away at both sides ofthe Scope Ring until it’s completely flat. When finished, removetheScope Ring fromthe lapping filmand inspectit for any remaining high spots or irregularities.

What is a Lapping Bar?

A lapping bar is a tool that is used to create a smooth, level surface on a workpiece. It consists of a long, narrow strip of metal with abrasive material bonded to one side. The abrasive side is rubbed against the workpiece in a back-and-forth motion until the desired finish is achieved.

Lapping bars are available in a variety of sizes and grits to suit different applications.

Is Lapping Scope Rings Really Necessary?

No, lapping scope rings is not really necessary. While it can sometimes help with alignment and getting a tight fit, it’s not required for most installations. If you’re having trouble mounting your scope or getting it to sit level, then lapping the rings may help.

But in general, it’s not something you need to do.

Cheap Way to Lap Scope Rings

Lapping scope rings is a process of polishing the mating surfaces of the scope ring halves so they fit perfectly together. This ensures that your scope is mounted securely and won’t move or shift, which can cause problems with your aiming. There are a few different ways that you can lap scope rings, but the most common and cheapest way is to use sandpaper.

All you need is some fine grit sandpaper (around 600 grit or higher) and a flat surface to work on. To start, place a piece of sandpaper down on your work surface and then set one of the scope ring halves on top of it, making sure that the part of the ring that will be in contact with the other half is facing down onto the sandpaper. Then, simply hold the ring in place and rub it back-and-forth across the sandpaper until you’ve achieved a smooth, even finish.

Repeat this process with the other half of the scope ring until both mating surfaces are perfectly lapped. Once you’re finished lapping, it’s important to clean off any residual debris from bothscope ring halves before mounting them onto your rifle. A quick wipe down with a clean cloth should do the trick.

Then just screw them together tightly and mount your scope – you’re ready to shoot!


Lapping is the process of polishing the inner surface of a ring so that it is perfectly flat. This is important because when you mount a scope onto your rifle, you want the rings to be as close to the scope as possible. The closer the fit, the better the chance of getting a clear image through your scope.

There are two ways to lap scope rings: by hand or with a machine. If you choose to do it by hand, you will need some lapping compound and a piece of fine sandpaper. Apply a small amount of lapping compound to the inside of one ring, then place the sandpaper on top and rub in a circular motion until the surface is smooth.

Repeat with the other ring. If you have access to a lapping machine, simply follow the instructions that come with it. Either way, once you’re finished lapping, make sure to clean off all of the residue before mounting your scope.
