I've got a non-F marked FSB that came with a barrel, and while I'd prefer to just trade it for an f-marked, I need a BUIS anyway.  so my question, are there any BUIS that will work w/ a standard A2 FSB without cranking the front sight up above the ears?  thank you and drive thru.

They all will work, but yes you may have more elevation or depression on the front in order to zero.  That said, there are some taller front sight post out there....I think Bushmaster sells one.  Would suggest you try to zero first as it would not make good reasoning just to get the taller FSP and need to depress your sight.  This is far from a hopeless situation. Most every early M16A4 had standard FSB, but they did change them later.

well, the rifle's not even together yet, piecing everything together slowly as budget allows, so planning on what to get now, hence the question.  would the taller front sight post also stick up above the ears?  would a carry handle a2 work?  or wha?  thanks
