This flash hider has a unique patent-pending design featuring mass shifted equal length tines. The end result is a flash hider that does not ping. It is compatible with the Sandman-L, Sandman-S, Sandman-K, and KeyMo equipped Nomad-30 or Primal suppressors. Note: Flash hider bores are sized to the thread pitch. (Ex: 1/2×28 is bored to .224 to meet the 5.56 requirement. 5/8×24 is bored to .30 cal.)
