[ARCHIVED THREAD] - National match sight conversion

Posted: 12/17/2016 1:44:15 PM EDT

I'm building a dissapator rifle mostly because the of parts that I have left over from a national match build. My main problem is that for the short range, fast shooting that I will be doing, the current rear sight on the A2 NM upper is super tiny. The upper is a dpms, can I swap it with this part and it be a drop in?

Thanks for looking!

Maybe. Depends on how the 1/2 or 1/4 MOA value was achieved, ie dual offset detent balls in the knob or a different thread.

Compare your thread to a pic of a standard A2's.

Replace your NM windage screw and aperture with std. USGI parts. The windage screw hole in the sight body is usually not modified.
