As the title says. I'm browsing for a 30 cal can that will eventually be used on a 300blk 8" - 9" barrel (subs and supers) and have narrowed it down to these two.  For those who have experience with both, would you recommend one over the other?  The Polo is cheaper, but doesn't include a mount (aside from the direct thread) so I would probably go Griffin Plan A if I went with the Polo. The Razor is more, but comes ready to go out of the box. Both are reported to have fantastic warranties and manufacturer support, so they both have that going for them.

Thoughts?

Personally I see that a a plus in the Polonium column.  You can use whatever mount is best for your needs. It's Hub threaded so all your cans can use the same mount.

Rugged forces you into their own proprietary mount whether it's best for you or not. Whether you have cans from other manufacturers or not.

A non Hub can has to be exceptionally good and have an exceptionally good price for me to even consider buying it.
