Has anyone tried to fit a jp adjustable gas block under the new BCM Keymod 13" handgaurd? It looks very close to fitting. If anyone could give me some measurements, I would be thankful. The most important one would be the bottom of the block to the bottom of the barrel. I saw elsewhere in the forum the measurement from the top of the block to the top of the barrel was .408" that looks acceptable. I need to see if the bottom and the width where the adjustment screw is. Thanks.
