I recently installed a BCM ELW barrel and gas block with a Centurion CMR rail. As you can see, the bottom of the gas block is pretty much up against the rail. I was planning to just grind down the bottom of the gas block for a bit more clearance. Any downsides to doing this? There's plenty of room to remove material before I reach the screw heads. I've shaved a couple FSBs before, so this should be easy. And I'm not planning on any builds for a long while, so buying a different gas block just seems like a waste. Just wondering if I'm missing anything before I do it.
