Common Gunsmithing Services: What Can a Professional Gunsmith Do for Your Firearms

If you’ve ever searched “gun repair near me” after a stubborn malfunction, a gritty trigger, or a rifle that just won’t group the way it used to, you’ve already felt the value of a skilled gunsmith. A professional gunsmith doesn’t just “fix broken guns”—they diagnose problems, keep firearms running safely, improve performance, and help you customize your setup to fit your needs.

At RTF3TX, we’re a family-owned, privacy-focused, appointment-only shop led by AGI Certified Master Gunsmith Roland Lamothe (with co-owner Sandra Lamothe). We work on a wide range of platforms—especially centerfire rifles and pistols—and we’re known for clear communication, careful handling, and strict safety standards.

This guide breaks down the most common gunsmith services customers ask for—and the specific services we actually provide—so you know what’s possible, what to expect, and when it’s time to bring your firearm in.

Diagnostic and repair services

When something isn’t functioning correctly, the first job is always the same: diagnose the root cause. Many issues look identical on the surface (failure to feed, failure to eject, light primer strikes), but the fix depends on what’s actually happening inside the firearm.

Malfunction diagnostics and troubleshooting

We can help with common reliability problems such as:

• Failure to feed (FTF)

• Failure to fire

• Failure to eject (FTE)

• Failure to return to battery

• Double-feeds

• Extraction issues

• Cycling issues (short-stroking, inconsistent cycling)

What this looks like in real life: you might have a rifle that runs fine for 20–30 rounds, then starts choking; a pistol that occasionally fails to go fully into battery; or an AR that suddenly won’t lock back on empty. Those symptoms can come from multiple causes—springs, extractor tension, gas system behavior (platform-dependent), magazine issues, or simple wear.

A proper diagnostic appointment focuses on:

• Reproducing the issue (when possible)

• Inspecting high-wear components

• Checking function and timing (platform-dependent)

• Identifying whether the problem is parts-related, maintenance-related, or setup-related

Parts replacement and fitment

A big part of professional gun repair is replacing worn or broken components and ensuring proper fit and function afterward. Depending on the platform and issue, this can include:

• Replacing worn springs

• Replacing small parts that commonly fail (platform-dependent)

• Repairing or replacing damaged components as needed

• Verifying function after parts replacement

The key difference between “swapping parts” and professional gunsmith work is verification. After parts replacement, we confirm that the firearm cycles and functions correctly, and we look for the underlying reason the part failed in the first place (wear, tolerance stacking, improper installation, or maintenance issues).

Because we maintain eyes-on inventory checks and min-max stock levels for frequently used parts, we aim to reduce downtime on common repairs.

Barrel work and accuracy-related service

When accuracy drops or a firearm’s performance changes, barrel-related issues may be part of the story. We can evaluate and address barrel-related concerns as part of the diagnostic process.

If you’re seeing sudden changes in point of impact, poor grouping, or inconsistent performance, we’ll look at the full system so you’re not wasting time chasing the wrong fix. That may include:

• Evaluating barrel condition and wear

• Checking for obvious damage or abnormal fouling

• Verifying that your optic mounting and setup are not the real cause

• Looking at the interaction between ammunition, firearm, and setup

Platform coverage: what we work on regularly

We service a wide range of firearms, with regular work on:

• AR-15 platforms

• AK platforms (including AK74)

• M4-style rifles

• SCAR / “M17 SCAR” (as referenced by customers)

• Western lever actions

• Centerfire pistols

• Shotguns

If you’re unsure whether we can service your specific make/model, the fastest path is to book an appointment and tell us what you’re working with.

Maintenance and preventative services

The most cost-effective gun repair is the one you never need. Preventative maintenance keeps your firearm reliable, extends parts life, and helps you catch safety issues early.

Basic cleaning, deep cleaning, and suppressor cleaning

Cleaning isn’t just cosmetic. Carbon buildup, fouling, and neglected lubrication can create reliability issues that look like “mystery malfunctions.” We offer:

• Basic cleaning (for routine upkeep)

• Deep cleaning (for heavy fouling, long intervals, or hard use)

• Suppressor cleaning (to reduce buildup and keep performance consistent)

If you run your firearm hard (high round counts, training cycles, or suppressed shooting), professional cleaning can help prevent premature wear and keep function consistent. It also gives us a chance to spot early warning signs—springs that are losing tension, abnormal wear patterns, or parts that are nearing the end of their service life.

Safety inspections

If you’ve inherited a firearm, bought used, or simply want peace of mind before the next range trip, a safety inspection is a smart move. We can:

• Inspect overall condition and function

• Identify worn or unsafe components

• Flag issues that could become failures later

A safety inspection is also a great idea before a hunting season, a competition, or any time your firearm has been stored for a long period.

Refinishing and protective work

Wear happens—especially on working guns. We offer:

• Full gun bluing

• Refinishing services (as applicable to the firearm and finish type)

Refinishing can be about aesthetics, but it can also be about protection—helping reduce corrosion risk and extending the life of the firearm. If you’re dealing with surface wear, rust concerns, or a finish that’s simply been loved hard for years, refinishing can bring a firearm back to a cleaner, more protected state.

Customization and enhancements

Customization is where a good gunsmith can make a firearm feel like it was built for you. Whether you want a cleaner break, better ergonomics, or a more practical setup, professional customization focuses on reliability and safety first, then performance.

Trigger work (custom trigger jobs)

A trigger that’s too heavy, gritty, inconsistent, or unpredictable can hurt accuracy and confidence. We offer:

• Custom trigger jobs

A good trigger job is about more than “lighter.” It’s about creating a consistent feel you can control: a cleaner break, predictable reset, and a trigger you can run confidently for your intended use.

We’ll talk through your goals (carry, duty, hunting, competition, range use) and keep safety at the center of the work. If a customer asks for something that would compromise safe function, we’ll explain why and recommend a safer alternative.

Optics: scope mounting

If your optic isn’t mounted correctly, even the best rifle can’t perform. We offer:

• Scope mounting

Proper mounting matters because it affects:

• Repeatability (holding zero)

• Confidence in your data and adjustments

• Long-term reliability (preventing loose hardware and shifting)

If you’re chasing accuracy issues, scope mounting is one of the first places to verify—because a small mounting problem can look like a “barrel issue” or “ammo issue” from the bench.

AR-15 and AK maintenance and performance-oriented service

AR and AK platforms are popular because they’re adaptable—but that also means small changes can create big reliability differences.

We regularly provide:

• AR-15 maintenance

• AK maintenance

This can include diagnosing cycling issues, addressing wear-related problems, and helping your rifle run consistently after parts changes or hard use.

Accessories and practical upgrades

Many upgrades look simple online and turn into headaches at the bench. We can help you avoid mismatched parts, improper fitment, and reliability problems by installing and verifying accessories as part of a complete setup.

If you’re building a “do-everything” rifle, setting up a competition firearm, or simply trying to make your home-defense setup more usable, the goal is the same: a firearm that runs reliably and fits you well.

Stock and ergonomics-related guidance

Fit matters. If your rifle doesn’t shoulder consistently or your setup feels “off,” we can talk through practical changes that improve comfort, control, and repeatability.

If you have a specific stock, grip, or furniture upgrade in mind, bring the details to your appointment so we can confirm compatibility and help you avoid buying parts that don’t match your platform.

Specialized services

Some gunsmith work goes beyond routine maintenance and repairs. These services are about performance goals, long-term preservation, or building something truly personal.

Competition preparation

Competition firearms need to be reliable under pressure and consistent across high round counts. We can help you prepare by:

• Inspecting function and wear points

• Addressing reliability issues before they show up on match day

• Improving performance through appropriate trigger work and setup verification

If you tell us what you’re shooting (platform, caliber, optic, match type), we can tailor the work to your needs and prioritize the changes that actually move the needle.

Restorations and preservation-minded work

Older firearms and family heirlooms often need a careful approach—especially when the goal is to preserve value and character while restoring function.

We can evaluate restoration needs and discuss options, including refinishing and full gun bluing when appropriate. The goal is to balance appearance, protection, and function without turning an heirloom into something it was never meant to be.

Custom work and build planning

If you want a firearm built around your purpose—rather than forcing a “close enough” setup—we can help with custom work and build planning.

This can include:

• Platform selection guidance

• Reliability-focused assembly and verification

• Function testing and refinement

Bring your parts list or ideas—especially for AR/AK work—so we can confirm compatibility and a realistic plan before you spend money on parts that don’t play well together.

When to seek professional help

Some issues are obvious (broken parts, visible damage). Others are subtle—and those are often the ones that can become safety problems.

Consider booking a gunsmith appointment if:

• Your firearm has repeated malfunctions, even after basic cleaning

• You’re seeing light primer strikes, inconsistent ignition, or failures to extract/eject

• Accuracy suddenly drops and you can’t identify why

• Your trigger feels unsafe, unpredictable, or dramatically different than normal

• You’re installing an optic and want it mounted correctly the first time

• You’re running suppressed and want proper maintenance (including suppressor cleaning)

• You purchased a used firearm and want a safety inspection before relying on it

A quick safety note (and our shop policy)

Safety is non-negotiable. All firearms must be unloaded before service. Repeat violations of this policy will result in refusal of service. This protects you, our team, and every customer who trusts us with their firearms.

What to expect at RTF3TX

We operate by appointment only (no walk-ins). Most appointments run 30 minutes to 1 hour per firearm, depending on the service.

When you book, it helps to share:

• Firearm make/model and caliber

• A clear description of the issue (what happens, when it happens)

• Any recent changes (new ammo, new magazine, new optic, new parts)

• Your goal (repair, reliability, performance, restoration, customization)

That information helps us move faster, diagnose more accurately, and get you the best outcome.
