McCutchen Firearms — Precision .50 BMG and .416 Barrett Rifles and Uppers

Built to order · Ships in 1–3 business days · Free UPS Ground over $1,000 · 90-day no-interest financing

McCutchen Firearms builds AR-platform upper receivers and complete rifles chambered in .50 BMG and .416 Barrett — available in both single-shot and magazine-fed configurations. Our uppers mount directly to a standard AR-15 lower receiver, delivering big-bore precision in a familiar platform without the cost or complexity of a dedicated chassis rifle.

Every McCutchen upper and rifle is built from premium components and a Cerakote finish as a standard — a level of protection and finish quality most manufacturers reserve as an upgrade.

Orders are built from in-stock parts and typically ship within 1–3 business days. No multi-month backorders, no waiting on production runs — just a built-to-your-configuration rifle out the door fast.
