I have pieced together Colt M4 Upper Colt LWT 1/9 16" barrel (for a 6320) "F" Marked FSH Mepro Tritium Front sight YHM Riser Eotech 512 M4 handguards The question. I want a BUIS, but I want my front sight to be flush or near the FSB floor. I have seen images of front sights screwed down below normal or screwed up with threads exposed. Looks odd. Do I need a particular BUIS or is this a non issue and just go with my choice? I want it too look right. thanks in advance |

Having an F marked FSB is the best bet for keeping it below the ears. After that, there's not much you can do about it unless you want to file/mill the bottom of the rear sight so it sits lower on the rail. Tolerances will give you +/- a few thousandths, but all the sights are going to be approximately the same spec. |
