About
What it is, and why it matters
The Robar RC-50 is a custom-built single-shot bolt-action rifle chambered in .50 BMG, handcrafted by the Robar Companies of Phoenix, Arizona for precision long-range shooting. Each RC-50 is individually built to customer specifications, featuring Robar's proprietary NP3 nickel-phosphorus-PTFE finish for exceptional corrosion resistance and self-lubrication. The rifle emphasizes accuracy over rate of fire, with a match-grade barrel and precision-machined action delivering sub-MOA performance with quality ammunition.
The Robar RC-50 represents the boutique end of the .50 BMG market, where each rifle is handcrafted by gunsmiths who spent decades perfecting custom firearms finishing. Robar's NP3 treatment, originally developed for military and law enforcement applications, gives the RC-50 a distinctive satin appearance and requires virtually no lubrication, making it unusually low-maintenance for a precision rifle of this caliber.
Robar Companies is best known for their custom firearms finishing services, particularly their proprietary NP3 surface treatment that combines electroless nickel with PTFE (Teflon) particles for a self-lubricating, corrosion-resistant finish. The RC-50 showcases their capabilities in a complete rifle package. Each rifle is hand-built to order with extended lead times. The fiberglass composite stock provides a lightweight, weather-resistant platform that won't warp or shift in extreme conditions.
