Howdy Partner! Thought we should spend some time talking about gun barrel inspections. Regular firearm maintenance is essential not just for performance, but also for safety. Among the most effective tools for firearm inspection is the gun barrel borescope—a compact, precision instrument that allows gun owners, collectors, and gunsmiths to visually inspect the interior of barrels with clarity and detail. This tool plays a critical role in detecting wear, corrosion, and other types of damage that would otherwise go unnoticed during routine cleanings.
Understanding the Gun Barrel Borescope
A gun barrel borescope is a specially designed videoscope or optical device that provides a close-up view of the inside of a firearm’s barrel. It typically features a slim, semi-rigid, or flexible probe equipped with an LED light and a high-resolution camera. This probe is inserted into the barrel, allowing the user to view real-time footage on a screen or monitor. Today most folks use a videoscope with a micro camera at the tip of the probe. Videoscopes can capture pictures and videos with just the push of a button. Not to say that rigid borescopes or fiberscopes can’t do the job but taking pictures with these inspection tools is much more challenging.
Unlike traditional inspection tools, a borescope doesn’t just illuminate the barrel—it captures high-quality visuals that make it possible to assess subtle defects, deposits, or structural issues that may affect the firearm’s accuracy and safety.
Detecting Barrel Wear
One of the most common issues firearms face over time is barrel wear, especially in high-use weapons. Wear typically occurs around the throat and rifling areas that experience intense friction and pressure with every shot.
With a gun barrel borescope, you can closely examine:
- Erosion of the rifling near the chamber
- Worn lands and grooves that affect bullet stabilization
- Surface scouring and fine scratches caused by fouling or improper cleaning
Identifying these signs early allows you to determine if a barrel needs re-lapping, replacement, or simply more careful maintenance. In high-precision shooting, even minimal wear can alter ballistic performance.
Spotting Corrosion and Rust
Corrosion can quietly degrade a firearm’s barrel from the inside out—often beginning as microscopic pitting that spreads over time. Moisture, improper storage, and firing corrosive ammunition without thorough cleaning are frequent culprits.
A gun barrel borescope makes detecting corrosion far easier by:
- Revealing small rust spots or pitting along the bore
- Highlighting discoloration or uneven metal textures
- Helping users monitor the spread of corrosion over time
Even if a firearm appears clean from the outside, interior rust could be compromising its structural integrity and accuracy. Using a borescope ensures early detection and gives gun owners the opportunity to intervene before the damage becomes irreversible.
Identifying Cracks and Structural Damage
While less common, cracks, bulges, or gouges within the barrel can pose significant safety risks. These can result from overpressure rounds, barrel obstructions, or manufacturing defects. Since such damage is often difficult to see with the naked eye, a borescope becomes invaluable.
Using a borescope, you can:
- Detect stress fractures or unusual wear patterns
- View damage around the chamber or muzzle crown
- Document before-and-after visuals for insurance or repair purposes
For professional gunsmiths, this level of insight is essential in determining whether a firearm is safe to operate or needs retirement.
A Smart Investment for Gun Owners
Whether you’re a casual shooter, a seasoned hunter, or a firearm enthusiast, owning a gun barrel borescope empowers you to take control of your firearm’s maintenance. You’ll only have to pay for it once, but it will save you money in the long run because your guns will last longer and not need as many fixes or replacements.
Modern borescopes, like those with semi-rigid 3.9mm probes and forward-view cameras, offer the ideal combination of maneuverability and clarity for inspecting barrels of various calibers. A very popular option for larger caliber guns is a dual camera borescope. These borescope probes offer a straight view and a side view camera. With just the push of a button you can toggle between views. It’s like have two borescopes in one! Makes me happier than mouse in a hay barn!
The Benefits of Performing Gun Barrell Inspections
Better Maintenance Planning
Believe it or not there are folks that collect guns and never even shoot em! Gun collectors often own firearms that may not be fired regularly—or at all. However, infrequent use doesn’t eliminate the risk of internal barrel issues. In fact, long-term storage without inspection can lead to unnoticed rust or bore fouling, especially in humid environments or older storage cases.
Using a semi-rigid videoscope or handheld borescope makes routine rifle barrel inspection efficient and non-invasive. It allows collectors to set cleaning schedules based on the actual condition of the barrel rather than guesswork, helping to prevent over-cleaning or neglect.
Safer Occasional Shooting
Some collectors choose to fire their prized firearms occasionally to ensure they remain functional or simply for the joy of shooting a historical piece. In such cases, safety is paramount. Barrel obstructions, corrosion, or cracking can pose a serious hazard during firing.
A thorough inspection ensures the bore is clear and the rifling is intact. By regularly inspecting barrels, collectors can identify risks before pulling the trigger, helping to preserve both the firearm and their safety.
Why Barrel Inspection Matters
The inside of a rifle barrel may look smooth from the outside, but it undergoes intense pressure and heat with every shot. Over time, this can lead to a variety of problems:
- Copper Fouling: Residue from bullet jackets can accumulate in the grooves, affecting bullet spin and trajectory.
- Carbon Buildup: Unburned powder and debris can cling to the bore, impacting accuracy.
- Pitting and Corrosion: Moisture or corrosive ammunition can cause rust and pitting that erodes the barrel lining.
- Throat Erosion: The area just ahead of the chamber can degrade faster than the rest of the bore, leading to reduced performance.
- Residue Build Up: Residue from discharged ammunition can accumulate inside the barrel, leading to carbon buildup and possible fouling. This can reduce accuracy, cause malfunctions, and if you haven’t done it some time, make cleaning more difficult.
The Benefits of Regular Barrel Inspections
I reckon if you have read this far down my chattering, you’re going to want to know what’s in it for you! Incorporating rifle barrel inspections into your maintenance routine brings several advantages:
- Improved Accuracy: Spot and eliminate causes of poor shot placement.
- Extended Barrel Life: Address wear and corrosion early to avoid permanent damage.
- Informed Cleaning: Clean more precisely by knowing where the buildup is located.
- Safer Shooting: Ensure there are no obstructions or critical barrel faults before firing.
Whether you’re preparing for competition, evaluating a used firearm, or just maintaining your gear, regular use of a rifle barrel borescope can save time, money, and frustration.
Choosing the Right Videoscope
Are you ready to select your gun barrel borescope? Well, get your boots on and start kicking tires. There are many options to choose from. Take your time and make a good decision. You don’t want to jump at the first thing and end up bellyaching about it later. When selecting a videoscope for gun barrel inspection, consider the following features:
- Probe diameter: Ensure it fits the caliber(s) of your firearm.
- Viewing direction: Forward-view is ideal for straight inspection; side-view helps with chamber inspection.
- Focal Distance: What is the distance from the probe tip to it’s targeted image quality. For most gun barrel inspections, you don’t want a far focusing borescope.
- Length: A 1-meter probe is sufficient for most rifles and shotguns.
- Image quality: Look for HD resolution and adjustable LED lighting.
- Durability: Semi-rigid probes offer a good balance between flexibility and control.
- Documentation: You’ll want a borescope camera that takes pictures and videos. This way you can document your inspection and at minimum show off to your friends.
