Solidly built product with a satisfying heft. The mock flash hider friction fits very snugly on 19mm O.D. barrels such as the Worker SCAR with absolutely no play. The mock suppressor likewise threads very securely to the flash hider. This package stands out from the other Worker mock suppressors due to the fact that it is available in a completely orange finish as opposed to the mostly black finishes of their other offerings. This is thus a safe yet aesthetically appealing muzzle extension which I wholeheartedly recommend.
