So, I am putting together an AR-10(T) and am curious about BUIS. I bought a ggg folder that goes on the gasblock but still need to get rear buis. Will any AR-15 rear buis work? I am trying to stay as low as possible. I am not sure what optic I will be using, but it will be in an LT-104. I have seen that the KACs are the lowest available, but are graduated for distance. Will the tic marks for distance match up very well for use on an AR-10?
For the most part, all rear sights will work with the exception of the AR15 carry handle variety.
Arms 40L is pretty slim
KAC makes the slimmest I believe.
But just about any rear folding sight will work. So your options are wide on that sight. Its just the front youre limited on when using the gas block.
PRI makes a raised gas block so you can use same plane sights.
MI's SPLP....lays down to be .4375 of an inch and should fit under your scope...Depending on were you mount it and your particular scope...
