The Faxon Firearms 18" Big Gunner 6.5 Creedmoor AR-10 barrel is built for shooters who want accuracy without sacrificing handling. This 6.5 Creedmoor barrel combines a smart profile design with tough nitride coating to deliver precision on long-range hunts, competition stages, and the range. Machined from triple stress-relieved 416R stainless steel, it's engineered to run cool and stay accurate through strings of fire.
The Big Gunner profile is where Faxon's design smarts shine. It tapers like a government profile from the extension back to the gas block, then transitions to a pencil profile toward the muzzle. This isn't just splitting the difference—it's strategic weight removal that tames muzzle whip while keeping the rigidity where it matters, at the rear where heat and recoil forces are highest. That design also shifts your rifle's balance rearward, making an 18" barrel feel noticeably more maneuverable in the field or from a bench.
Faxon's 5R rifling and 1:8 twist rate stabilize 6.5 Creedmoor loads across a wide range of bullet weights while making bore cleaning straightforward. The QPQ Nitride finish—applied inside and out—resists wear and corrosion without adding bulk. The barrel arrives with an 11° target crown and a 5/8"-24 threaded muzzle, ready for your suppressor, brake, or flash hider. Each barrel is individually headspaced and tested before it ships, so you can build with confidence.
Fits DPMS LR-308 pattern upper receivers and runs standard rifle-length gas tubes, making it a drop-in choice for AR-10 builds.
| Caliber | 6.5 Creedmoor |
| Length | 18" |
| Twist Rate | 1:8" |
| Rifling | 5R |
| Material | 416R Stainless Steel (triple stress-relieved) |
| Finish | QPQ Nitride (matte black) |
| Muzzle Thread | 5/8"-24 |
| Crown | 11° target |
| Platform | DPMS LR-308 pattern |
| Gas System | Standard rifle-length |
Yes, if your upper follows the DPMS LR-308 pattern. This barrel is designed as a drop-in for that standard and uses a rifle-length gas tube.
The 1:8" twist is the standard for 6.5 Creedmoor and handles the full range of bullet weights commonly loaded in that cartridge. Faxon's 5R rifling also makes throat fouling less of an issue, so cleaning between sessions is easier.
Yes. The muzzle is threaded 5/8"-24, which is the standard suppressor thread for rifles in this caliber and size class. Any 5/8"-24 suppressor or muzzle device will fit.
The profile removes weight from the front of the barrel to reduce muzzle whip and keep your rifle balanced, while retaining stiffness at the rear where thermal and recoil forces matter most. This design improves both accuracy potential and maneuverability compared to a straight government or pencil profile.
