title says it all. tryin to finish up my first ar pistol build and i need some advice. which would be better the standard troy flip ups or the micro set? i have a rock river buffer tube no foam or rubber. i also have a gg&g accucam cantilever mount for a compm3. i am not too worried with co-witnessing but i want to have a good sight pic. thanks

looking at the hk style front, i have a monorail style setup on top

If you plan on using the buffer tube for a cheek weld the micros will be too low to see properly.  Those Micro sights, if I understand them correctly, are for rifles that have a higher than normal sight plane like the HK416.  If you mount the micro sights, or one from the HK416, you will find that you are looking over the rear sight even when your face is pressed firmly on the buffer tube.  I had this exact thing happen when I put a set of HK 416 sights on my pistol.  The foam cover on the buffer tube had me looking over the rear sight instead of through it so the foam had to come off.  IMO get the standard sights and keep things simple.
