Single Process Technology (SPT)

Velocity Arms has developed what they believe to be the most accurate pistol bore manufacturing process ever created. Single Process Technology means the bore, rifling, and chamber are cut in one high precision machine without human interference. 

What It Means...

Single Point Technology means the rifling is cut using the legendary and painstaking single point cutting technique. This single point cut rifling process requires a single cutter to make 120 individual cuts to accurately rifle each bore. Single point cutting yields identical grooves that have less than .0001" deviation between each other because they are being cut with the exact same cutter.

Better Performance

"Button" barrels and standard "cut" rifling can not achieve this kind of repeated accuracy due to normal tool wear and tool making tolerances. "Single point cut" barrels consistently hold better groove to groove concentricity to the bore. These two technologies combined produce barrels with tighter tolerances and true alignments on all features of the bore and chamber. All this equals superior accuracy down range.
