Accuracy International Ltd. and Cooper Precision
Manufacturing are proud to announce the availability
of their precision rifle barrels.
In response to increasing demands from the shooting industry, Accuracy lnternational Ltd. and Cooper Precision Manufacturing (CPM) are proud to offer 'Cut Rifled" barrels to the gunsmith trade. Since its inception twenty-one years ago, Accuracy International (AI) Ltd. has become a leading producer of precision rifles used for sport and by governments for defense, peacekeeping and internal security throughout the world. The company has gained an enormous amount of experience through constant research and development, customer comments and the implementation of production improvements. AI Ltd. maintains the coveted quality accreditation of BS EN ISO 9001 (1994) for the design and manufacture of small arms. AI Ltd. wishes to share these unequaled products and services with its customers. To this end, Accuracy International is proud to announce the availability of Cooper Precision Manufacturing (CPM) rifle barrels. CPM barrels are produced by applying the time-proven "Cut Rifle" method to only the highest quality 416 stainless gun barrel grade steel or chrome moly steel as required. Furthermore, each barrel is hand-lapped to absolute precision. Considerable investment in staff, plant and quality measuring equipment have provided increased output with unprecedented quality. The use of sophistcated CNC machines ensures dimensional repeatability, which is especially useful where interchangeability or complicated profiles and threads, such as those found on M14, AR10s and M16 barrels, are required. The investment in quality has ensured fine-shooting, accurate barrels. How do they know? Cooper Precision Manufacturing has its own range facilites where actual checks and comparisons are made for product quality verifications. CPM is proud to make these outstanding barrels available to custom rifle makers and target shooters. All popular calibers, from .22 LR to .50 cal., are available with many others available as time and demand permits. Current tooling allows CPM to offer the following barrels and dimensions: |
