AGI-Certified Master Gunsmith San Antonio
Precision Firearm Diagnostics & Repair, Custom Machining & Action Tuning

Master Gunsmith Roland Lamothe with shotgun

When a firearm fails to feed, misfires, or develops mechanical timing issues, throwing replacement parts at the problem rarely solves the root cause. RTF3TX Gunsmithing, led by US Army Veteran and AGI-Certified Master Gunsmith Roland Lamothe, delivers master-level mechanical diagnostics, precision machining, hand-fitting, and custom restoration for clients across San Antonio, Live Oak, Universal City, Converse, Schertz, and the Texas Hill Country.

Trained under master gunsmiths Bob Dunlap, Gene Kelly, and Gene Shuey at the American Gunsmith Institute (AGI), Roland applies complete mastery of firearm design, function, and mechanical engineering to diagnose and repair every system safely and reliably.

Beyond Parts Swapping: True Master-Level Diagnostics & Mechanical RepairServices Offered

 

The Master Gunsmith Difference vs. An Armorer

  • The Armorer Approach: An armorer is trained to perform basic assembly/disassembly and swap out factory-standard parts. If a firearm has tolerance stacking, worn locking geometry, or an obsolete component, standard parts swapping cannot fix it.

  • The Master Gunsmith Approach: An AGI-Certified Master Gunsmith understands the mechanical design, operating physics, and tolerances of all firearm actions. We diagnose why a failure occurred, recut and polish contact surfaces, custom-machine one-off components when parts don't exist, and tune actions for reliable performance.

Common Mechanical & Cycling Malfunctions We Solve

  • Feeding & Chambering Failures: Feed ramp profiling and mirror polishing, extractor tension balancing, chamber re-cutting, and magazine feed-lip geometry correction.

  • Extraction & Ejection Failures: Eliminating stovepipes and failure-to-extract issues through extractor tuning, ejector timing adjustment, and gas port regulation.

  • Light Primer Strikes & Ignition Inconsistencies: Mainspring tuning, firing pin protrusion calibration, channel decarbonization, and hammer-fall clearance trueing.

  • Trigger Group Timing & Sear Engagement: Removing trigger creep, setting crisp breaks, resetting disconnector timing, and eliminating hammer-follow.

  • Headspace & Accuracy Anomalies: SAAMI-specification Go/No-Go chamber gauging, locking lug contact lap, barrel torque verification, and muzzle crown recutting.

  • Stuck Casings & Chamber Clearances: Safe extraction of stuck rounds, chamber burnishing, and pressure anomaly diagnostics.

Comprehensive Action Types & Platforms Serviced

We service, repair, and tune all modern, vintage, and custom platforms:

  • Semi-Automatic Handguns: 1911/2011 custom builds, striker-fired platforms, and steel-frame duty models.

  • Revolvers: Single-Action and Double-Action mechanical timing, cylinder gap alignment, crane alignment, and endshake elimination.

  • Rifles (Bolt-Action, Semi-Auto, Lever-Action): AR-platform gas regulation, match bolt-action blue-printing, classic lever-action feeding, and surplus military arms.

  • Shotguns (Pump, Semi-Auto, Break-Action): Shell latch calibration, inertia system tuning, action bar alignment, and ejector timing.

Our 4-Stage Mechanical Diagnostic & Safety Inspection Protocol

Every project brought to our Live Oak workshop follows a rigorous diagnostic standard:

  1. Complete Teardown & Structural Inspection: Full disassembly to inspect all primary and secondary components for micro-fractures, stress wear, and previous improper alterations.

  2. Tolerances, Headspacing & Clearance Diagnostics: Precise measurement using optical inspection tools, micrometers, and precision Go/No-Go gauges to evaluate chamber dimensions and locking clearances.

  3. Precision Machining, Custom Hand-Fitting & Component Repair: Installation of high-grade OEM or aftermarket components. For obsolete or vintage pieces, in-house machining, lathe operations, micro-welding, and hand-stoning are used to restore or fabricate parts.

  4. Bench Testing & Mechanical Proof Verification: Comprehensive mechanical cycling and proof verification to confirm complete mechanical safety, proper lockup, and positive reset.

Frequently Asked Questions

Q: What is the difference between an armorer and a master gunsmith?

A: An armorer is trained to replace standard factory parts on specific models. An AGI-Certified Master Gunsmith possesses comprehensive mechanical engineering knowledge across all firearm platforms—able to diagnose root failure causes, machine one-off parts, adjust timing, and repair obsolete or custom equipment that standard parts cannot fix.

Q: How long does a standard diagnostic and repair take?

A: Standard bench diagnostics, tune-ups, and direct component replacements are typically completed within 3 to 7 business days. Custom machining, fabrication, or hard-to-source vintage parts may require 2 to 3 weeks. You will receive an exact timeline upon initial bench inspection.

Q: Do you accept walk-ins or are services by appointment?

A: To ensure dedicated attention and maintain strict workshop safety standards, services are scheduled primarily by appointment. You can book a convenient drop-off time through our Online Booking Portal or by calling (210) 740-1811.

Q: Can you repair obsolete, antique, or custom firearms with no factory parts available?

A: Yes. We do not rely solely on prefabricated factory parts. We utilize precision lathe operations, milling, and micro-welding to fabricate or rebuild custom one-off components to bring legacy firearms back to safe working order.
