OP Rod Question.......

I'm just about to pull out what little hair I still have.

My Springer loaded op rod just does not want to come out, . . . then does not want to go back in.

How can that be fixed by me, . . . or can it???

Thanks, may God bless,
Dwight

Once you get it out, round off the top corners of the tab until it goes in and out without trouble. I noticed Bula op-rods already have the corners rounded which means easy in and easy out.

The receiver often has a bit of a "shelf" in the oprod disconnect notch. That is where it is getting hung up.

Some folks modify the oprod tab, some stone the edge of the "shelf" in the notch.

When removing the oprod, you can tape up a large flat-head screw driver and use it to pry the top of the oprod hump away from the receiver. You can then use a mallet to tap the oprod up into the notch. This usually takes 3 hands.

Whatever you do, do it verrrry slowly and check your work twice. Just a friendly reminder:)

Kurt, I have found that my SAI oprod is actually more difficult to remove over time. I used to be able to get it out easily. Now it comes out but more effort needed.

I would have thought the opposite with use and wear.
Any idea on why or am I just loosing my touch getting it off?

You're lucky it's tight. With a worn op rod tab it can jump track while firing.

By not modifying the receiver shelf or the oprod tab, there is a good chance that you are flattening the edge of tab, making the issue worse.

You need to examine the tab under a jewelers leupe or magnifying glass. I would also examine the shelf in the disconnect notch. It could have a burr.

Thanks, Tony, . . . I saw that video last night, . . . and I still had to give it a really good whack to get it loose.

It has been a while since I had the gun apart simply because of other things taking up my time, . . . I even went in and got my spare op rod to see if I had it in the right "place" to get it out. I was sure I was right, . . . but checked anyway.

Still had to whack it.

I'll be taking a stone to that dude sometime in the forseeable future.

May God bless,
Dwight

Thanks from tonyben

I ronded the corners a bit, . . . didn't seem to make much if any difference.

THEN, . . . I didn't notice this before, . . . but really did not "look" for problems before, . . . my son and I are shooting more now, . . . so I'm "more into it" so to speak.

Anyway, . . . my op rod appears to be bent, . . . or is this within the "norm" of a Springer loaded M1A??

I compared it with another rod I have, . . . which seems to be much straighter, . . .

May God bless,
Dwight

Oprods do not bend easily. Check your oprod guide on the barrel to see if it has shifted.

Thanks KurtC, . . . and everyone else who chimed in.

The guide was solid, . . . no movement, . . . did not appear to have shifted.

BUT, . . . I had the answer laying in my bedroom.

I've been "in the process" of building a .22 M14 for about 5 years or so, . . . and had my spare op rod in the gym bag with all those other parts.

Got it out, . . . checked them one against the other, . . . my original on my Springfield Armory Loaded, . . . is bent, . . . the other one is not.

Tried Tonyben's "tip test" with both, . . . the bent one hung up when fully retracted, . . . the "spare" one works just like the video shows it should.

"Thank You", . . . and a tip of my USN Whitehat to Tonyben for the video and all of you who chimed in. Great to have folks that are willing to help out.

Took it out and ran a few rounds through it to see if it'll work should I need it, . . . bingo-bango, . . . all is good.

May God bless,
Dwight

Fantastic! Glad to see it all worked out! :)

Op-rods can bend if you're running really hot loads. Have you run a lot of M118LR or 180 grain loads out of it?

Tony.

Tony.
Would Wolff or Tubb springs prevent damage to the op rod from hot loads via slowing down the op rod and holding the bolt locked for slightly longer?
