Three dimensional laser scanning technology, originally developed for NASA, provides extremely detailed measurements throughout the entire length of the barrel. LP sensors act as “laser calipers”, taking a succession of single-point measurements of the distance between the probe and the rifling creating a 3D data point cloud, all without touching the surface of the barrel.

We measure and certify the internal dimensions of every rifle barrel we produce in order to ensure each barrel meets our exact quality control standards.

For Screening New Machined Barrels

– Certifying dimensional accuracy of machined barrels.
– Accurately measuring land and bore diameter across the length of barrel. 

– Certifying characteristics like Twist Rate, Groove Width, and Groove Depth, origin of rifling and generating graphs for the same. 
– Plotting Average land and groove diameter and average groove width across the length of the barrel 
– Highly capable in accurately measuring groove diameter for rifling with odd number of grooves. (5 groove barrel) 

– Plotting Runout of grooves as compared to the bore across the length of the barrel. 
– Generating Visual Graphics to identify and detect features, machining flaws and defects.

Lance scanning services provide you with detailed information about your barrel.  Send us your barrel to be Three Dimensional Laser scanned and find out the exact details of your barrel.  Call us today at 605-341-3006!
