The SPR is the Navy's version of an 18" medium range sniper/marksmans rifle. While the #12 variation may have the Ops brake on it, that doesn't mean it's particularly suited for team or urban use - exactly when you might need a light.
Muzzle brakes with lots of side blast aren't used in CQB teamwork, you don't want to be stacked in a team with one next to your helmet. The Levang forward or standard flash hider is preferred. Cost also gets into the equation - for $180, you don't get 15X the recoil reduction of GI, and the AR15 isn't known as a major recoil producer. Brakes on them are upper tier parts used by competitors on three gun ranges, or those with the need for multiple shots. Unless you're prairie dog hunting - which wasn't mentioned - then the actual value of the brake won't ever be realized.
As for lighting up a coyote, there's the Gen III nightvision to consider, or infrared, or in combination. Any good red light would do otherwise.
