Is there a stickie thread on front sight blocks? With the different uppers and FSB's available, is there a thread with dimensions for the difference between A2 and A3 parts? The reason I ask is that I have a standard flat top and a 'gun show' barrel. I sighted it through the barrel and then through the iron sights and it seems to be pretty close at 45' with the adjustments about centered. (the distance between the kitchen counter and the card taped to the living room wall) Close enough to get me on the paper at 100 feet anyway.
I couldn't find an 'F' on the FSB and I know there is a difference between the two. Not much but enough to run out of adjustment on the sights sometimes. |
