Overview

Bartlein 5R cut rifling in a 3.6 lb carbon fiber .270 blank

The Bartlein .270 carbon fiber barrel blank is a 5R cut-rifled stainless steel core wrapped in carbon fiber, sold unchambered for a gunsmith to fit. This is the #13 Varmint/Sendero contour, 1:7.5 twist, 26 inch finish length. Other contours and lengths are available to order.

5R single-point cut rifling

Five lands with a gentler side angle than conventional rifling, and an odd count so no land sits directly opposite another. The gentler angles reduce bullet jacket deformation when the bullet engages the rifling.

Stainless core, carbon wrap

A full-length stainless steel liner carries the .270" bore, with 2.75" of bare steel at the breech before the carbon wrap begins. The resin has been tested stable past 500 degrees F.

3.6 lb at 26 inch

#13 Varmint/Sendero contour steps from a 1.200" breech to .950" and tapers to an .830" muzzle, 3.6 lb at 26" finish length.

Hand-lapped and ready to finish

Bartlein hand-laps each 5R cut, which requires a minimum 1.0" muzzle cut to remove bell-mouth. The blank ships 1" longer than the finish length you order, and your gunsmith will chamber, thread, crown and install it.

Fitment

Will it work with your build?

Works with

  • Bolt-action rifles being rebarreled by a gunsmith for a .270 cartridge
  • .270 cartridges such as .270 Win, .270 WSM, 6.8mm Rem Spc and other .270 bore cartridges
  • Suppressors: muzzle diameter .830" is above Bartlein's .700" minimum

Will not work with

  • Gas guns (AR-10 and similar): Bartlein does not make gas-gun barrels
  • Pre-fit 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 26 inch finish length you are ordering 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. Bartlein 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: Bartlein hand-laps each cut-rifled barrel, which can bell-mouth the muzzle, so at least 1.0" must come off the muzzle end. Chambering removes the same effect at the breech.
