Proof Research PR15 .223 Wylde AR-15 Barrel - Rifle Length - Medium - Carbon Fiber - 18"

The Proof Research PR15 is a carbon fiber wrapped AR-15 barrel that cuts weight while keeping the accuracy and reliability of a stainless steel core. Built for lightweight hunting, competition, and general-purpose AR-15 builds, this barrel delivers a CAMGAS tuned gas port and a 5/8x24 threaded muzzle.

Features:

• Carbon fiber wrapped 416R stainless steel
• .223 Wylde chamber
• Rifle-length gas system
• Gas journal for .750 gas blocks
• 5/8x24 threaded muzzle
• CAMGAS tuned gas port
• Made in the USA

Proof wraps a stainless steel barrel core in aerospace-grade carbon fiber impregnated with a proprietary matrix resin, which reduces weight by up to 64 percent compared with a steel barrel of similar contour. The wrap also improves heat dissipation, which helps hold point of impact during sustained fire and reduces harmonic vibration.

The 18-inch length with rifle-length gas system adds velocity and offers a smooth recoil impulse, and the .223 Wylde chamber handles both 5.56 NATO and .223 Remington ammunition. The CAMGAS process tunes the gas port to the cartridge and gas system length for smooth, reliable cycling. A .750-inch gas journal pairs with standard gas blocks, and the 5/8x24 muzzle threads accept flash hiders, compensators, and suppressor mounts. The barrel arrives chambered and ready to install on an AR-15 upper receiver.

Proof Research, based in Columbia Falls, Montana, pioneered carbon fiber wrapped rifle barrels and manufactures its barrels in the USA.
