NOTICE TO END-USER: Most of our products including; (but not limited to) barrel blanks, are for domestic (Canadian) use ONLY. Exporting any of these products outside of Canada is expressly PROHIBITED under I.T.A.R. and E.A.R. laws and regulations; enforced by the U.S. State Department and the U.S. Commerce Department.
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.
We pre-lap our barrels before rifling and finish lap the barrel after rifling. There is no need or under any circumstances, should you fire lap or do any other sort of bore polishing to the barrel. Contrary to what others say, a lapped barrel will not wear out earlier vs. an unlapped one. In our experience, our barrels will typically last longer than a button barrel, etc.
