Diamondback DB Barrel — 6.5 Creedmoor, 24" Rifle-Length, Black Nitride, 4150 Chrome Moly Vanadium Steel | Model 65CR24M50B8 (UPC: 815875019138)
Stretch your effective range and tighten groups with the Diamondback DB 6.5 Creedmoor 24" Barrel. Purpose-built for precision and durability, this barrel is machined from 4150 Chrome Moly Vanadium (CMV) steel and finished in a black nitride (QPQ) treatment for exceptional wear resistance, corrosion protection, and smooth bore characteristics. The 24-inch length maximizes velocity for flatter trajectories and stronger downrange energy—ideal for long-range target work, PRS-style training, and open-country hunting. A rifle-length gas system helps deliver a softer, more consistent recoil impulse for rapid follow-up shots and stable point of impact.
Why Choose This Diamondback 24" 6.5 Creedmoor Barrel?
Long-Range Advantage: The 24" length helps unlock the 6.5 Creedmoor’s ballistic potential, typically producing higher muzzle velocity and reduced wind drift versus shorter barrels.
Duty-Grade Construction: 4150 CMV steel is renowned for strength and heat tolerance under sustained fire.
Black Nitride (QPQ) Finish: Enhances surface hardness, resists rust, and reduces fouling—making clean-up faster and preserving accuracy.
Rifle-Length Gas System: Promotes smoother cycling, less felt recoil, and improved component longevity.
AR-Pattern Friendly: Designed for AR-10/LR-308-style builds chambered in 6.5 Creedmoor (verify compatibility with your upper/BCG pattern).

Performance Benefits You’ll Notice
Flatter Trajectory & Stronger DOPE: Extra barrel length typically means higher velocity, helping shrink wind calls and elevate long-range consistency.
Temperature & Erosion Resistance: Nitride-treated CMV steel mitigates throat wear and makes copper/carbon fouling easier to manage.
Smoother Shooting: The rifle-length gas system contributes to a controlled recoil pulse, aiding spot-your-own-impact feedback.
Consistency Over Strings: A rigid 24" profile supports stable harmonics for repeatable groups with quality ammo and a tuned handload.
Ideal Use Cases
Long-Range Target & Steel: PRS-style practice, club matches, and distance work from 600 to 1,000 yards and beyond.
Open-Country Hunting: Take advantage of 6.5 Creedmoor’s accuracy and sectional density for ethical shots at extended ranges (where lawful and with proper judgment).
Precision Recce/DMR Builds: Pair with a free-float handguard, quality mount, and a crisp trigger for a highly capable precision semi-auto.

Installation Tips
Prep & Inspect: Degrease the extension and journal; lightly oil mating surfaces.
Torque Right: Follow proper barrel nut torque procedures and index per your upper system.
Align the Gas Block: Dimple or pin when appropriate; use thread locker per manufacturer guidance.
Headspace Check: Always verify with GO/NO-GO gauges.
Season & Verify: Confirm gas function, then zero and build a DOPE card with your chosen load.

Frequently Asked Questions
Q: Why pick 24" over 20"?
A: 24 inches typically yields higher velocity, giving you flatter trajectories and slightly less wind drift—useful for extreme-range shooting.
Q: Is nitride better than stainless?
A: Black nitride on 4150 CMV provides a hard, corrosion-resistant surface and easy cleaning. 416R stainless is also popular for precision. Choice depends on your environment and maintenance preference.
Q: What twist rate should I use for heavy bullets?
A: Many 6.5 Creedmoor builds favor 1:8 for 120–147gr projectiles. Confirm the twist on your specific barrel run to match your load.
Q: Will this fit my AR-15?
A: No. 6.5 Creedmoor barrels are for large-frame AR (AR-10/LR-308) platforms, not AR-15 receivers.
