Description
About Structured Barrels®
_____________________________
Overview
Ultra-high performance barrels with internal and external geometries machined from a monolithic barrel blank.
_____________________________
Advantages
- Adds +30% stiffness (compared to a barrel of similar weight) for less flexion and a smoother recoil impulse.
- Adds +300% surface area for heat dissipation to minimize thermal mirage, flatter SDs, and improved life.
- Light-weight and fits a standard chassis.

Terms and Conditions
Agreement
PLEASE READ CAREFULLY. Submitting payment acknowledges having read and agreeing to the terms and conditions provided herein. If you do not agree, do not submit payment.
Size, Length, and Geometries
Blanks are not guaranteed to finish at or under the specified Diameter. All Structured Barrels taper up or down to fit the action. Thus, the neck and action may be different diameters. Gunsmithing requires the barrel to final length per vendor specification*. TACOM HQ processes all blanks at raw length.
*Removal at muzzle per vendor specification:
Bartlein -1″
Benchmark -1″
Krieger -1″
KS Arms -2″
Outlier -1″
Tenon Length
Calibers smaller than a .338 will have 1.5″ available for a tenon.
Calibers equal to or greater than a .338 will have 2.0″ available for a tenon.
*Custom tenon lengths available upon request.
Twist Rate
Click here to use the Twist Rate Stability Calculator by Berger to evaluate different conditions. Achieve a high stability factor to ensure bullets do not prematurely destabilize at distance.
Drop-shipping
Drop-shipped blanks must be a straight contour from chamber to muzzle, be .250-inches larger than Max Finish Diameter, and must include a TACOM HQ Purchase Order (PO). Removal of a nipple or similar feature at the muzzle is required to be processed. Failure to do so will incur additional charges. Blanks unclaimed within 90-days of delivery will be marked abandoned, automatically circulated into production, and sold without reimbursement or credit.
Borescopes
To maximize barrel life, borescopes are recommended to ensure comprehensive and consistent bore cleaning.
Indemnification
Customer assumes complete responsibility for order selections. Customer further indemnifies TACOM HQ of all liabilities for any discovered defects from a barrel manufacturer that includes but not limited to rifling, bore, and material.
