Adam –
Picked up this 4 rail gas block for a pistol build where the removable rails are a necessary feature. I am impressed at the quality of the design, the rails hold firmly and it has three set screws to hold it on the barrel. The finish is the only downside, but its pretty good for such a low cost gas block. I like this block with the removable rails a lot more than the non removable 4 rail ones that clamp through the lower rail. These rails are all usable.
