6315RF-A1, LH is a .223, 1/2 x 28 (internal) flash suppressor / suppressor mount for 1x16 LH (external) threaded sound suppressors and suppressor adapters.

It features internal grooves for improved flash suppression, these grooves are functional and not decorations.

Bigger isn't always better The grooves serve to reduce both the immediate flash and the secondary flash. However the small difference, we'd rather have the reduction than without.
