I noticed when I first bought my rifle the standard M4 handguard was off maybe1/16" compared to gas block. I figured I could live.with it. I just bought an Eotech 5512,now if I ever decided to with a magnifier I would have to make room. I would have the buis the magnifier and the eo.
I tried moving the eo forward to make room, as I move it forward the canted barrel nut/ rail it moves the sight up and off center slightly but enough to drive me nuts. Do I send it back to have the barrel nut retourqed? Kinda at a loss. |

Have you removed it to check the alignment of the nut? |

Those are just drop in handgaurds.
They don't always line up excatly. Your barrel nut is just a hair off, It would have to bee moved to fix it but it is not worth it. You are not trying to mount a front sight to the Handguard right, so it should not matter. There should be able to mount Your magnifier and Eo-tech with the correct mounts and still have room with the BUIS making the rail irrelevent. Like This.

You could get an EOTech riser set up for lower 1/3 cowitness that would also allow you to move it further forward on the upper. Posted Via AR15.Com Mobile |

No, don't dump the back up. Take it to a gunshop that works on AR's, have them correctly index the barrel nut. Then you can bridge the gap without worrying about the cant of the hand guard. |

Quoted: This is starting to become and even more $$$ endeavor that I had anticipated. There has to be a cheaper route. And now you guys have me thinking I need to raise it up to 1/3rd either way now. The cheaper route is to use the EO without a magnifier. You should be able to make hits out to 300 yards on steel easily with no magnifier. Practice.

I like that idea better, and that was my intentions. I am over thinking it I believe. Quoted:
