Overview
A .30 caliber carbon fiber barrel blank with 5R cut rifling, ready for your gunsmith
The Benchmark Barrels .30 caliber carbon fiber barrel blank is a lightweight blank for a gunsmith to chamber, thread and install. It comes in Sendero and Sendero Light contours, with 1:9 and 1:10 twist options in 20, 22, 24 and 26 inch finish lengths. All barrels are double hand lapped and individually stress relieved.
5R single-point cut rifling
Five lands with an odd count provide consistent grip on the bullet jacket. Cut rifling puts no stress into the blank.
416R and 4140R carbon steel core
Stainless steel grades ensure corrosion resistance and longevity. The core is fully wrapped in carbon fiber for weight savings.
Two contours, two twists
Choose Sendero or Sendero Light, and 1:9 or 1:10 twist. All combinations are offered in 20, 22, 24 and 26 inch finish lengths, with 1" extra for the gunsmith to cut and crown.
Double hand lapped, stress relieved
Each blank is individually hand lapped to a consistent bore and double stress relieved using Benchmark's proprietary techniques. Quality control includes both proprietary and industry-standard inspection methods.
CNC chambering and threading
Benchmark uses modern CNC and fixturing to produce the straightest and most uniform threads and chambers in the industry.

Fitment
Will it work with your build?
Works with
- Bolt-action rifles being rebarreled by a gunsmith for .30 caliber cartridges
- Suppressors, once the finished muzzle diameter is checked against the mount
Will not work with
- Gas guns (AR-10 platform): Benchmark does not make gas-gun barrels
- Pre-fit or drop-in installs: this blank has no chamber, thread or crown
This is a blank, not a finished barrel. It must be chambered, threaded, crowned and installed by a qualified gunsmith, and the finish length you choose is the length after the extra 1" is cut from the muzzle. Rifle barrels ship for a flat $14.95 per order, any quantity, and do not qualify for free shipping.
Detail
Fitting it and the fine print
Is this a finished barrel?
No. Benchmark Barrels sells blanks only, no pre-fits and no gas-gun barrels. Your gunsmith chambers, threads, crowns and installs it. Every blank is 1" longer than the finish length you order, left on for the gunsmith to cut from the muzzle end after inspecting the bore.
Which twist do I order, 1:9 or 1:10?
Order the twist the bullet maker lists for the bullets you plan to shoot. Both are available on every contour and length combination.
Which contour do I order, Sendero or Sendero Light?
The Sendero Light is the lighter, thinner contour. The Sendero is a heavier, stiffer profile that resists movement as the barrel heats, and is also Benchmark's recommendation where precision and suppressor use matter. Both are available in all finish lengths and twist rates. Other contours are available to order.
