It isn't a beer can opener, though.

Noveske barrels...polygonal rifling...

I am going back and forth between a Trijicon RMR, Reflex and Aimpoint of some sort. RMR is probably going to win.

In fact, I did just order the Ace Tactical Bottle Opener for my Picante rail. Can't wait to get it out to the Sheriff's range.

I already have a LaRue Tactical Beverage Entry Tool...

What is a polygonal rifling? POF uses a 5R polygonal rifling.

Most barrels have a round hole then grooves are cut into the sides of the cylinder. At that point the twist is added, so you have a spiraling set of lands and grooves.

For polygonal rifling, some sort of shape with multiple sides (i.e. polygon) is cut into the barrel then it is twisted. So the lands and grooves are more gradual and subtle being formed by the corners of the polygon.

It is supposed to have a few advantages; more backpressure, more even backpressure on all sides of the bullet, easier to clean and less wear.

I am guessing that 5R means an octogon is the shape POF uses as their polygon shape. H&K and now Glock use polygonal rifling as well. Apparently it is more expensive since Noveske barrels are typically $500+.

Hope that helps,
Mark
