I think you'll be thoroughly satisfied. I have a Krieger barrel and a Bartlein with canted rifling...besides the factory Remington. The Bartlein feels as smooth as silk when I clean it after a shooting session...and it's clean in no time. All of my 5R barrels have been exceptionally easy to clean. Can't say whether there is any gain in velocity to be had.....but they've all been excellent shooting barrels.

Good Luck.....I envy you for being able to have a suppressor....Some day I'll move to a state that allows it :).
