My favorite sb-tactical brace yet! - SB Tactical SBA5 5 Position Adjustable Rifle Brace

I had high hopes for this brace, but was still surprised by how well it works. I replaced my SBA3 that I've been using on my AR-15 "Pistol", and the difference (when using it like all non-disabled individuals "occasionally/accidentally" do) is night and day. Because of it's design geometry and the noticeably firmer/less-flexible material used in its construction combine to make it feel (if a user were to accidentally, of course, slip and happen to put it against their shoulder/chest) like a legitimate and comfortable stock. I'm extremely happy with my purchase, especially at the low price O.P. had it "On Sale" for (and the very quick shipping after I submitted my Order).

As a bonus, I also happen to be one of the people who thinks it looks even better than the other options (including my SBA3), although I know that opinions are mixed about that (at least from the Reviews and gun-forum discussions I've seen since its release).
