I'm not sure if the 5R Rifling will help with a bit of FPS. I herd is a tiny bit faster than regular.
Not enough to be meaningful. Some 5R barrels will be slower than conventional 4 or 6 groove rifling.
Polygonal rifling has been unilaterally faster for me for a given barrel length, but I wouldn’t go out of my way to buy poly rifled barrels just for that reason.
