I am looking at different BUIS configurations. Will I run into issues of compatibility among different manufacturers? Will a Troy flip up rear line up with the stock, fixed front on an RRA Entry M4? What if I replaced the gas bolock with an integrated flip sight like YHM. Would that line up with the Troy or other manufacturers? Thanks |
