Bartlein Barrels

The uniformity in our barrels and finish of the bores is second to none. Our rifling machines are so accurate we can carry the twist rate to the 4th decimal point (example: 11.3642). The process of Single Point Cut Rifling is the most stress free way to rifle a barrel. The twist is exact where as other forms of rifling can have variances due to the process they use. Also the bore and groove dimensions are more uniform.
