Monk Customs Helix Outer Barrel - Gold

This is Monk's latest addition to the world of M4 Outer Barrels.

The unique and stylish twisted helix design stands out beautifully, especially when used in combination with a Monk-style skeletonized hand guard!

The clever O-ring addition makes sure the inner barrel is always positioned in the center of the Helix Outer Barrel and sits tight!
