Full description and what we offer
Spartan Precision Rifles is a licensed FFL/SOT shop specializing in custom rifle builds and advanced gunsmithing on modern bolt-action platforms. Located in Caldwell, they work by appointment only and handle everything from complete rifle builds to specialized barrel work and action truing.
They work on: - Remington 700 and clones (Defiance, Surgeon, Stiller, ARC, Bighorn) - Winchester Model 70 - Accuracy International - Savage bolt actions - Ruger RPR
They explicitly do NOT accept handgun or AR-15 work—this is precision rifle territory.
Complete builds (Spartan sources all parts): 10-12 months depending on parts availability. Deposits typically run $2,500-$3,000.
Customer-supplied builds: 2-4 weeks of labor once parts arrive. No deposit required until completion.
Barrel jobs (replacement only, no bedding): 4-8 weeks
Stock paint jobs: About a month depending on complexity

Actions: Defiance, Surgeon, Impact, Stiller, Curtis, BAT Machine, Barnard, American Rifle Company
Stocks: Manners, McMillan

Reamers: They prefer JGS Precision and support 30+ calibers including .223 Remington, 6mm Dasher, 6.5 Creedmoor, .308 Winchester, .300 PRC, .338 Lapua Mag, .375 Cheytac, and wildcats.
- •Barrel Dialing: Every barrel is dialed in to within ±.0002" of bore center-line using precision-ground tapered indicating rods and a Mitutoyo dial indicator. They dial through the headstock, not over the ways.
- •Barrel Fluting: Done after chambering to prevent flute interference and ensure perfect top-center alignment with the receiver.
- •Shipping: Licensed to accept firearms directly via UPS/FedEx without going through a local dealer. If you haven't completed an ATF Form 4473, they'll ship to your chosen FFL for the background check.

Pro tip: Don't ship parts without calling first. Include your name, contact info, and a description of what you want done. They won't accept parts trickling in over time—send everything at once when you have it all together.
