Purchased my first suppressor (polonium K)
Wondering if anyone has run the Comstock armory recessed micro brake and their RPA hub on BCM (preferably 16 inch barrel with 15 inch mcmr rail)

The rail is 15 inches to the flare, don’t know if the RPA will clear the rail, or if I should just get the LPA instead to be safe.
