You can get around that with the right tool and or planning ahead with your handguard. If the adjustment screw is on the side it’s an easy fix. If it’s in the front you can order long Allen wrenches for cheap. There is also an upscale brand of free floater that is lever removable (Fortis Switch) I wouldn’t have an adjustable block on a rifle that I couldn’t readily adjust.Check out at3 Tactical video section on how to install. As far as adjusting it the side screw shouldn't be tightened down until you see a consistent ejection pattern between 3 to 4 o'clock range. When adjusting do not have your handguard installed so you can make your adjustments easily. Happy shooting.
