The cut rifling process is the oldest form of rifling in the industry to date; this traces its roots back to the early 1500s in Nuremberg

It is also the slowest form of rifling as it takes an average of 30 to 40 minutes per barrel, compared to the 15 or so seconds it takes for a button to be pulled. This is due to the fact that we are only removing 0.0001 of an inch each pass of the cutting tool. We use custom made cutter box's containing a single point, carbide tipped cutting tool. These carbide cutters are uniquely ground for each individual rifling twist to ensure we get correct groove dimension and no ratchet rifling.

Our two primary cut rifling machines are Pratt & Whitney Sine Bars, one configured for 4 groove and one for 6 Groove. With these machines we have a rifling twist range of 1 in 6 to infinity. The process itself also allows us to have a greater flexibility in bore and groove size for any given calibre, this can cater for clients needs when using their products in hot or cold climates or specific ammunition is being fired.

All cut rifled barrel blank steel is fully heat treated and stress relieved before any machining takes place, and of course each barrel is hand lapped to give unrivalled twist/dimension uniformity. This truly gives us a bore and groove finish that's verging on mirror like quality which greatly reduces copper and carbon build up over a long-sustained period of firing. This has been backed up by client feedback and R&D work over a number of years.

We believe that if you truly want the utmost accuracy and consistency over extreme long range, a cut rifled barrel is the way forward.
