I can't dismount the op rod from the receiver. The dismount notice looks way too small. Usually only light finger pressure is required to dismount the op rod. IF I can ever get this thing out, I am considering reducing the dimentions of the guide stud on the op rod. Any suggestions?

Please provide the dimensions of the stud. I'll check and repost in a few days when I'm back.
Have you checked for straightness? If the Op Rod is bent, that could also be causing the problem. |

45V50 Gary: Op rod looks straight. I'm assuming you mean a really obvious bend or kink. This M1A is new and I haven't been pounding the bolt open or anything. Can't provide the dismount stud dimentions until I get the dang thing off. It's nothing like my old M1 Garand, which was a piece of cake to dismount. Thanks.

The Op Rod Receiver guide stud should be .100"-.005" (width). It's height should be .320"-.003" and length .330"-.010".
If you're rod isn't bent (hopefully not), there could also be a problem with your receiver (out of spec for dismounting notch or guide notch) or burr in the guide stud slot. |

Op rod still resisting my efforts. Thanks for the specs. When, and if I get this thing out, I'll check it out. I'm going try to get my hands on a different unit and check out the notch and etc. Thanks again.

I suspect that the rod is bent. It'll be hard to tell until you actually remove it from the receiver.

I got the op rod off finally. It doesn't look "bent". It measures just under for the dimentions: 0.100 for width, 0.317 for height, and 0.329 for length. But it's not a "clean" looking piece of machining on the stud. I'm gonna give Fulton Armory a call and maybe talk to them about a replacement or maybe some "home gunsmithing". Thanks for all the replies and stay safe.
