Prices for threading a gun barrel vary by caliber, safety considerations, and thread pitch, plus labor time. Typical cost drivers include the barrel diameter, the required thread length, the thread angle, and whether any finishing or profiling is needed. The following ranges reflect common pricing from U.S. gunsmiths and hobby shops.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Barrel Threading Service | $60 | $120 | $250 | Base labor plus setup; longer barrels cost more |
| Per-Inch Threading Rate | $4 | $10 | $20 | Dependent on thread pitch (e.g., 1/2-28, 5/8-24) |
| Thread Protector / Cap | $10 | $25 | $60 | Optional accessory |
| Facing / Crown Work | $15 | $40 | $120 | Often required for consistent protection |
| Coatings / Treatments | $0 | $25 | $100 | Oil, nitrate, or parkerized finish adds cost |
| Material & Tools Fees | $0 | $15 | $50 | If special tools are needed |
Overview Of Costs
Cost ranges reflect typical customer pricing for standard service on common rifle and pistol barrels in the United States. The total project often includes a base threading charge plus per-inch fees, plus any refinishing or protection accessories. Assumptions: standard mid-length barrels, common thread pitches, no exotic alloys, and no engraving or additional modifications. Assumptions: region, specs, labor hours.
Cost Breakdown
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor | $40 | $90 | $180 | Includes setup, alignment, and test-fitting |
| Materials | $0 | $15 | $50 | Tools and minor consumables |
| Route & Thread Pitch Options | $0 | $10 | $30 | Common 1/2-28, 5/8-24; special pitches add cost |
| Finish / Coating | $0 | $25 | $100 | Oil, parkerizing, or black oxide |
| Accessories | $0 | $15 | $60 | Protectors or adapters |
| Permits / Compliance | $0 | $0 | $0 | Typically not required for private owners in many states |
| Taxes | $0 | $6 | $25 | Depends on locale |
What Drives Price
Barrel diameter, thread pitch, and required length are the primary price drivers. For example, a standard rifle barrel with a 1/2-28 thread may cost less than a longer pistol barrel that needs a 5/8-24 thread. Additional factors include finishing requirements, whether the work requires holding fixtures or custom tooling, and the need for re-crowning or chamber work. data-formula=”labor_hours × hourly_rate”>
Pricing Variables
Two niche-specific drivers include thread pitch compatibility with common suppressors and the barrel’s material hardness. A 1/2-28 or 5/8-24 thread is common for many accessories; rare or non-standard threads raise prices. Harder barrels (stainless vs. carbon) may require specialized tooling and longer setup time, affecting the labor portion. Assumptions: region, specs, labor hours.
Regional Price Differences
Prices vary by region due to labor markets and shop demand. In the Midwest, threading may trend toward the lower end of the spectrum, while coastal cities often see higher quotes due to higher shop rates. Rural shops may offer the most affordable options, with urban shops providing faster turnaround at a premium. The delta across regions can be ±15–30% for the same service. Assumptions: standard pitch, average barrel length.
Labor & Installation Time
Turnaround time influences total cost when rush service is requested. Typical jobs require 1–2 hours of shop time for a basic thread and test-fit, plus additional time for finishing. If a shop must order special tooling or perform additional safety checks, labor can exceed the typical window. Assumptions: standard pitch, no defects requiring extra work.
Additional & Hidden Costs
Hidden costs may include inspection fees, shipping to and from the gunsmith, and handling charges. Some shops charge a minimum fee even if the work is minor. If a barrel needs re-crowning, headspacing verification, or additional threading for a longer attachment, expect incremental increases. Assumptions: no serial-number work or engraving.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes.
Basic Scenario — Short barrel, standard 1/2-28 thread, minimal finishing. Specs: 16″ rifle barrel, no excess length. Labor: 1.0 hour; Materials: $0; Per-inch: 6″ @ $6/in. Total: $60–$120.
Mid-Range Scenario — Moderate barrel length, 5/8-24 thread, light finishing. Specs: 20″ barrel, crown work. Labor: 1.5 hours; Per-inch: 8″ @ $8/in; Finish: $25. Total: $140–$220.
Premium Scenario — Long barrel, exotic material, specialty thread, additional protectors. Specs: 24″ barrel, 5/8-24 + crown + coating. Labor: 2.5 hours; Per-inch: 14″ @ $12/in; Finish: $80; Protector: $40. Total: $360–$520.
Assumptions: region, specs, labor hours.
Note: The figures above assume no major defect, standard safety checks, and no engraving or other modifications. Prices reflect typical U.S. market quotes from licensed gunsmiths and may vary by shop and locality. Assumptions: region, specs, labor hours.
