Cant say for 100% sure, but I do believe that there have been two different size locking rings on the DD tubes. Some older ones that were bulkier and interfered with the EoTech hanging off the receiver, and newer ones that were smaller and caused no problems. I dont know this for sure, but I had this same problem with one of the older DD rails I had used. When I asked here about the same problem, it was mentioned that there may be an oler series with a larger ring and that this would not be a problem with newer rails. Sure enough, the next batch of rails I got in did not have this problem?
Out of curiosity, when/where did you get that DD rail? |

Can anyone post comparison photos of the "new" DD ring next to the older style? I have no idea which one I have.

My RRA upper with a 9.0 DD rail is about three months old. I cannot mount the EOTech too far forward and hang over the end of the flattop. The locking nut seems to be too large for the EOTech to fit.
I now have an Aimpoint on the rifle now. Installed the EOTech on another upper with a YHM M/L quad rail and it fits perfect. I have said before here, the YHM quad rail is one well machined forearm and is well worth the money. 77Bronc |

I have a RRA mid-length w/factory installed DD 9.0 rail. 4 months old. My Eotech 552 w/Larue mount, will straddle between the receiver and the DD just fine. No problems
