Faxon makes great gas blocks, but it depends on the type you are looking for. Their low-profile gas blocks have worked great for my 20" barrels. I prefer SLR for my adjustable gas blocks. https://slrrifleworks.com/index.php?rout...y&path=125

Or you can just cut the front sight off and leave the original, if it will fit under your hand guard.https://www.youtube.com/watch?v=5sBqDpi-Cb4

I've taken and whacked the top of the A2 FSB off, filed the sharp edges good and round, then cold blued the cut surfaces. Looked and worked like a nice low pro block and best of all it uses the existing taper pins slots in the barrel.
