If your looking to reduce felt recoil, DO NOT HAVE YOUR RIFLE MAGNA-PORTED.
This process was designed for big bore handguns to help control muzzle jump. It was not intended to be used on rifles by design but has been misused for along time in this mannor.
THe magna-port system will not reduce felt recoil. All it will do is keep the muzzle down which actually transmits more recoil energy to your shoulder in a straighter line.
When the rifle lifts in recoil, it absords alot of that recoil energy. When it is kept from doing this, your shoulder gets all the recoil energy transmitted to it.
Just to prove my point, Magna-Ports owner Mr. Kelly had to design a system called Magna-Brake with is an actual muzzle brake
designed to do what the porting will not, reduce felt recoil.
If you want to stop muzzle jump, go ahead, if you want to reduce felt recoil, do it right and use a brake.
In my shop I highly recommend the Holland Quick Discharge muzzle brakes
and have yet to have a customer not be totally amazed with the amount of recoil reduction they got. They are simply amazing and the only brake I will use is the customer does not demand something else.
