Absolutely love it looks amazing on my esg
Great product.
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!
* These will fit the Article one with the Red Engines, not with the all Black
