Hi guys,I own a post-ban Colt AR15 with a 20" 5,56 NATO barrel. I'd like to change my post-ban front sight (.750) with a pre-ban one (with the bayo lug). The problem is that I bought a pre-ban front sight but there is a difference in the position of the 2 holes of the pins. I'd like to know if I can find a pre-ban front sight with the pins holes in the same position of the ones of my post-ban sight. Can somebody help me? Thank You very much. PS:I want the bayo lug only for aesthetic purpose. Bye Mauri |

Weldox, All is not lost. You can drill and tap the sight base for set screws. The benefit of this is now your front sight is windage adjustable for a mechanical zero with your rear sight. You need a 8/36 or 8/32 tap set($3.50) and (4) corresponding set screws(about 3/16" long). Just tap the existing holes and put the screws in. Set screws are usually used in conjunction with milled flats on barrels. I have not experienced any movement of the frontsights on my barrels that were previously pinned. |
| The problem is that the sight base and barrel are drilled together at the factory without thought of ever replacing the sight base. I agree with the set screw idea since this is how the sight base is attached to ALL match rifles (also with some locktite for extra security) |
