Burn Proof Gear Jumbo Shrimp Heavy Suppressor Cover 5.75" x 1.75"

Burn Proof Gear lists this as the Heavy suppressor cover in the Jumbo Shrimp size, 5.75 inches by 1.75 inches, in black. Covers exist for two reasons: they keep a hot can from cooking everything it touches, and they cut the mirage that rolls off a suppressor after a string of fire and wrecks the sight picture behind it.

Sizing is the whole job with a cover. Match the 5.75 inch by 1.75 inch figure to the can you are covering rather than to the caliber it is rated for, because two suppressors with the same bore can be very different lengths and diameters.
