Rhino EDM Progressive Porting

After 120 days of testing all sizes, shapes, and designs of ports, our computerized design out-performs all other porting available. This is accomplished with less wad sheer due to a one-and-a-half degree of entry to our ports.

These ports have virtually no leading edge to cut or shear the wads, which produces the large amount of plastic buildup in the holes and barrel. When the wad has been cut by porting, the shot has less protection from deformation in the choke are. Our design of elongated ports that are not at 90 degrees create no plastic buildup in them.

Barrel Porting

Not only do we offer the 13 holes on each side of the barrel via EDM Progressive Porting, we also offer 6 hole porting on each side of the barrel. Rhino barrel porting is the most advanced in the world today. Top American shooters, including Brad Kidd and Kory Kruse, have all made comments that the secret to speed is in the economy of motion. Both of these shooters said that they never lost sight acquisition of the target they were shooting once the trigger was pulled.

They also said they were able to fire the second round at the next target with an unbelievable amount of less muzzle rise. Both said they had never experienced anything like this before. Our porting reduces muzzle jump by a minimum of 87%.

Forcing Cone Lengthened & Polished

This procedure changes the internal angle of the transition area from chamber to barrel. Most guns are backboard and shooters believe that forcing cones have already been installed, but this is incorrect.

We use special tools to change the angle and then lap the barrel and hone it to a mirror finish. The results are 18% to 21% improvement in more uniform patterns, as well as 11% to 14% reduction of recoil and shot deformation. This is because the transition is not so abrupt as the wads and pellets pass this speed bump in your barrel.

GraCoil® Recoil Reduction Unit

This is a system that is designed for those who are recoil sensitive. One system is adjustable up, down, left, and right at the recoil pad area. The other system is also adjustable in this manner, but also has adjustable in and out features for length of pull. These systems are also adjustable in tension and weight for more or less recoil. Each system is custom installed with a lightning-fast turnaround time.
