Remington XP-100 First-Year .221 Fireball Bolt-Action Pistol | 10.75-Inch Vent-Rib Barrel, Mohawk Brown Nylon Stock
Introduced in 1963, this first-year Remington XP-100 helped launch the high-velocity .221 Fireball cartridge and set the standard for bolt-action handguns. Serial number 8666 places it within the inaugural 5,564-unit production run, and it retains all of the hallmark features collectors look for: a 10.75-inch vent-rib barrel, DuPont Zytel 101 Mohawk Brown stock with white diamond inlay, and the distinctive flared target grip.

What’s Included
- Remington XP-100 single-shot pistol
The XP-100 is built on a chrome-moly steel receiver and barrel, both finished in a deep blue that complements the Mohawk Brown nylon stock. The molded checkering and white tip spacer add visual detail while maintaining a secure grip.
Its 10.75-inch vent-rib barrel balances length with portability, extracting maximum performance from the .221 Fireball while keeping the pistol compact. The rib also reduces glare for a clearer sight picture.
A rear-locking bolt action delivers the rigidity and accuracy Remington’s engineers intended. Paired with fully adjustable iron sights—a ramp front and micrometer-style rear—the platform is ready for precise target work without modifications.
As a first-year example, this XP-100 represents the beginning of Remington’s venture into purpose-built bolt-action handguns, making it both a functional shooter and a collectible milestone. With only light handling marks, it remains an excellent specimen of a design that influenced the specialty-pistol market for decades.
