I know this is not 100% the place to ask this but I figure the people here know more about this question so here goes:
Can a std height pinned FSB be used on a A4 flat upper and still retain proper sight alignment. I know there is a word for it but I forget. I ask this because I've bought a couple of new FN 20" barrels, date stamped 2010 and they both had std. FSB. Thank you =) |

Thank you =) If you have any issues zeroing, you can install a taller front sight post into the FSB. I had to do this with a 20" AWB era Colt barrel that I installed in a flattop receiver, and ran an A3 carry handle. Colt and others sell the taller post. SAW has them here: http://www.specializedarmament.com/products/Front_Sight_Post_9mm_SMG-221-289.html |
