Barrel blanks for professional gunsmith machining
A barrel blank is a precision-made steel semi-finished product with a rifled or smooth bore, intended for further professional machining. It is not a finished barrel ready for installation in a firearm.
Our range includes shorter and longer barrel blanks suitable for rifle, pistol, shotgun and percussion applications. Individual variants may differ in caliber, length, outer diameter, twist rate, number of grooves, material and manufacturing method.
Barrel blanks can be used for the manufacture of new barrels, replacement barrels and custom gunsmithing projects. Always check the specifications stated on the individual product page before placing your order.
Select the blank according to the required caliber and the intended firearm or gunsmithing project.
Check that the dimensions provide sufficient material for final profiling, threading and fitting.
The appropriate twist rate depends primarily on the caliber, bullet length, bullet weight and intended use.
The steel grade, manufacturing method and number of grooves may vary depending on the selected product.

Frequently Asked Questions (FAQ)
What is the difference between a barrel blank and a finished barrel?
A barrel blank is a semi-finished product intended for further machining. It normally requires chambering, external profiling, threading, fitting and other operations before it can become a finished firearm barrel.
Do the barrel blanks have a chamber?
Unless explicitly stated otherwise in the product description, the barrel blanks are supplied without a finished chamber. The chamber must be machined later for the selected cartridge and firearm design.
Can a barrel blank be purchased in Slovakia without a firearms licence?
Yes. Under Slovak Act No. 190/2003 Z. z., a barrel is considered a main firearm component and is defined as including a chamber. The barrel blanks offered by Barrel22 are unfinished blanks without a chamber and may therefore be purchased in Slovakia without a firearms licence. Machining a blank into a finished barrel and installing it in a firearm must be carried out by a person holding the appropriate authorisation. Customers outside Slovakia must comply with the laws of the destination country.
How do I choose the correct barrel blank?
Consider the required caliber, blank length, outer diameter, twist rate, number of grooves and material. The blank must also provide enough material for the planned final dimensions and machining operations. If you are unsure, consult the gunsmith who will carry out the work before ordering.
What does the twist rate mean?
Twist rate indicates the distance over which a projectile completes one full rotation inside the bore. For example, a twist rate of 1:10" means one full rotation in 10 inches. The optimal twist depends mainly on the caliber and the length and weight of the projectile.
Do all barrel blanks have the same technical specifications?
No. The available products may differ in caliber, length, outer diameter, twist rate, number of grooves, steel grade and manufacturing method. The specifications listed on the individual product page always apply to the selected variant.
What if the required caliber or dimensions are not listed?
Please contact us at info@barrel22.eu and provide the required caliber, length, outer diameter and other relevant parameters. We will check the available options.
Who may machine a barrel blank?
Machining that turns a blank into a finished barrel, as well as its installation in a firearm, should only be performed by a suitably qualified and authorised person. All work must comply with the laws applicable in the country where it is carried out.
