[ARCHIVED THREAD] - Which front sight post?

Posted: 5/22/2006 8:39:26 AM EDT

My ar has an A1 upper receiver with an M4 barrel(F marked front sight base). It shoots low with the front sight post in the all the way down position. Is there a front sight post that would work better than the one that came with the barrel?

Thanks for any help on this.

If that happened to me, I would just carefully file the post down squarely about 1/16" and attempt another re-zero. Then I'd touch up the tip of the post with some flat black krylon when I was finished.

That looks like what I may have to do.

Not sure if this would apply to your case, but Bushmaster sells a "short" front sight post. I think itt's about 0.040" shorter. It's in their standard catalog.
