I have many builds with low profile gas blocks, but they required purchasing front sights. To save money I decided to get the all in one FSB (which is a gas block with fixed front sight.) I bought 4 of these F marked FSB for the price of one lo-pro plus one flipup. I have not installed any yet, only test fitting on the barrels and they look like quality. My package was missing all the taper pins, but no matter, I plan on drilling with #21 drillbit and using 10-32 set screws.
