PROOF Research AR-Style Barrel — 6.5 Creedmoor, 24" | Rifle +2 Gas | 1:8" Twist | 4 Grooves | 5/8-24 TPI | Carbon Fiber Wrapped | SKU 100059 | UPC 843068100059
Unlock long-range precision without the front-end weight. The PROOF Research 6.5 Creedmoor AR-Style Barrel (24") features a match-grade stainless steel core that’s carbon fiber wrapped to deliver bolt-gun accuracy with a dramatic reduction in mass and faster heat dissipation. Tuned with a Rifle +2 length gas system for smooth cycling and softer recoil impulse, this barrel is purpose-built for competition, hunting, and any AR-10 pattern rifle that demands sub-MOA performance at distance—without the fatigue of a heavy front end.
Why Choose a PROOF Carbon Fiber Barrel for 6.5 Creedmoor?
Lightweight, no-compromise accuracy: Carbon fiber dramatically cuts weight while maintaining the rigidity of a heavy contour, promoting repeatable harmonics and consistent precision.
Runs cooler, recovers faster: Carbon fiber’s superior thermal conductivity helps shed heat quickly, reducing POI shift during long strings and getting you back on target sooner.
Optimized gas dynamics: The Rifle +2 system lengthens dwell time for smoother cycling, reduced bolt speed, and improved reliability—especially with suppressed setups.
Match-grade construction: A hand-lapped stainless steel core with 4-groove rifling and a 1:8" twist stabilizes popular 6.5 Creeds—from 120-grain high-BC bullets to heavier 140+ grain match loads.
Ready for modern muzzle devices: The 5/8-24 TPI muzzle threads accept brakes, flash hiders, and suppressor mounts used across the AR-10 ecosystem.

Real Advantages You’ll Feel on the Rifle
Balance that moves with you: The weight savings at the muzzle translate to faster transitions, steadier holds in field positions, and less fatigue in long matches or hunts.
Repeatable cold/warms bore shots: Enhanced stiffness and thermal management reduce wandering POI and help maintain tight vertical in extended shot strings.
Cleaner recoil impulse: The long gas system and 6.5 Creedmoor cartridge combine for a flat, trackable recoil signature—see more impact and spot your own shots.
Ideal Use Cases
Precision Rifle Competition (gas gun divisions) where quick follow-ups and consistent heat management matter.
Western big-game hunting at extended ranges with challenging terrain and long hikes.
Range/steel work for those chasing first-round hits from mid to long range.
Suppressed setups looking for smoother gas and minimal POI shift.
Installation & Setup Tips
Verify pattern & fit: This is an AR-10/SR-25 pattern barrel. Confirm upper receiver compatibility (DPMS/SR-25 pattern) and gas-block journal specs.
Use quality components: Pair with a matched bolt carrier group, properly headspaced for best results, and a low-profile gas block aligned to the Rifle +2 port.
Torque & align: Follow PROOF- and receiver-maker torque specs; ensure true alignment of the gas block and gas tube.
Break-in & zero: While the bore is hand-lapped, a brief break-in and careful zeroing with your match or hunting load can tighten groups and stabilize POI.
Tune for perfection: Consider an adjustable gas block and buffer tuning (and/or suppressor setting) to dial recoil and ejection with your ammo.
Ammo & Twist Guidance
1:8" twist loves popular 6.5 Creedmoor bullets: 120–130 gr hunting and PRS options, 136–147 gr long-range match loads.
Expect excellent stability and BC retention for minimal wind drift and tight vertical at distance.
Maintenance & Care
Clean as you would a premium stainless match barrel; avoid aggressive steel tools.
Let the barrel cool between long strings—carbon fiber helps, but good heat discipline preserves peak accuracy.
Keep the crown and threads protected when removing muzzle devices; use a quality protector or install your brake/mount with appropriate torque and Rocksett/Loctite as recommended.
