5-inch Inconel 625 5.56 suppressor, 11.50 oz, HUB 1.375x24, ships with a 1/2x28 HUB Mounted Brake.

Fortitude 5.56 HD is the Inconel 625 5.56 suppressor in the Polite Society pair. It measures 5.00 inches, 1.69 inches in diameter, and 11.50 oz, printed as one piece and finished in Cerakote. The rear is HUB 1.375x24. It ships with a 1/2x28 HUB Mounted Brake carrying an integrated flash hider.
The company describes Tripass Core as a central bore plus two helical bypasses into expansion chambers, and says the layout does not induce backpressure. Treat that as a manufacturer claim. No independent sound, backpressure, or minimum-barrel data is published. Rated calibers are .223 Remington and 5.56 NATO.
Buy the HD when the host will see heat and volume. The titanium twin is the same size and list price at 6.40 oz. Warranty is original-purchaser repair, replace, or refund of MSRP.
