    About Black Hole Weaponry

    Specialists in Polygonal Rifling, Black Hole Weaponry is located in Central Washington State. We are a Division of Columbia River Arms LLC. Black Hole Weaponry is owned and operated by Carl Caudle who has been a gunsmith for over 30 years.

    We use 416R  stainless steel and our rifling shape is a series of arcs instead of square corners, as in the traditional style of Enfield rifling. This arc shaped rifling has long been held in very high regard for its accuracy, increased velocity, reduced gas cutting and ease of cleaning.  Here you can see the difference between classic Enfield rifling compared to the 5 land and 3 land polygonal rifling. 

    • We purchase certified material and keep certifications on file.
    • We record material lot numbers and track each piece of steel through the entire manufacturing process.
    • We mark each barrel near the extension with our name, the lot number and the inspectors stamp.
    • We perform magnetic particle inspections and other non-destructive testing
    • Every barrel is individually inspected using industry standard Go/No-Go gauges with an Industry standard bolt. 
    • We randomly employ destructive testing methods
