No rifle is going to cycle with blanks unless you are using a blank fire adapter like this.
AR-15/M16 Blank-Firing Adapter
The AR-15 Blank Fire Adapter is designed to allow you to create enough backpressure to cycle your AR-15 when using blank ammunition. The blank fire adapter easily slips over the flash hider of your rifle and can be adjusted to find the correct amount of backpressure for your rifle.www.keepshooting.com
Without the bullet providing a restriction the gas pressure in the barrel is a tiny fraction of what it should be.
I made that point way back in the thread, but it was ignored.

You took it to the range once, both before and after reinstalling the gas block ?

Like others said a blank does not build any pressure with an open muzzle.
Forget about blanks and go to the range once you have the new gas block.

It wasn't ignored. I fired my service rifle without a blank adaptor without an issue . But more importantly, I cant go to range every time I adjust the gas block . number three, I push the muzzle into a bucket of old rags to kill the noise and help retain the pressure.

holddover it doesn't work like that. lets wait to test this the proper way. don't waste more blanks

The fact thay you can't go to the range every time you make a change doesn't alter the physics that says a blank will not cycle a properly working AR without a BFA.
And you might sometimes get it to cycle with a bucket of rags like you say, but that isn’t a reliable way to test, so it shows you nothing useful.

I have fired my AR with blanks without an adapter and without a problem , so saying it doesn't work , isn't very convincing . I completely understand your premise , but I have done it with no issues . Not disagreeing that its not the best indicator. Less pressure, I get it . But Im working with what I got.
The bucket of rags was used to silence the report ( which it did very well, less than a balloon pop.) so my neighbor doesn't get me swatted out , I was also hoping to contain the pressure a bit , but that was secondary to the noise.

Update!
I decided to take matters into my own hands and used a #39, 0.0995, to drill out gas port. It basically shaved the hole a little bit , and I bought a gas block jig to make sure it matched up perfectly. I fired a blank through it , and it did not cycle, Grrrrrrrrrrrrrr! I fired a blank through my other carbine and it did not cycle. I packed up my gear and took it to the range and it fired and cycled perfectly .
So to you guys who said blanks would not cycle , Salute! You were correct. (Although I did fire my service weapon without the adaptor before which is why I was so pig headed about it.)
So Im not so clear on which reason was the cause , the port hole or the alignment because I did not test it when I drilled my porthole. only after I got the gas block jig . But it any case, its working , and I would recommend the gas block jig for 12 bucks . You could make your own , its nothing complicated

Im told them that , but my gun still didn't fire.
Nah, it's more likely the gas block was off a smidge ,

Everyone makes mistakes. No one is perfect.
Glad you got it fixed and sorry you had so much frustration to get to this point.

Yeah, Live and learn. But now I know how to do it right.
