I have an m-4 barreled upper that shoots 24 inches high at 25 yards. The rear sight is all the way down, using the 0-2 aperture. If I unscrew the front pin 1/4 inch, it shoots 6 inches high. I have tried several diffrent ammos in it, all the same. What is the problem? Besides shooter error. How do I fix this? Is there taller front pins? should I need one of these? thanks. tom |
| Bushmaster has a .040" taller front sight post, that should correct your problem. Look here; Bushmaster FSP |
