Working on my supervisors rifle, He bought the upper from another co-worker already built.
There were a number of issues, but the one I am fighting right now is the buffer tube. The tube sounds funny. Kind of like a noisy zipper, or a zip tie.
I swapped in a buffer and spring from my rifle which helped a lot, but did not entirely fix the problem
I swapped his spring back in, no difference.
So at this point I am thinking its 80% the buffer and 20% the tube itself.
Which brings me to my next issue. The buffer tube seems to be some sort of enhanced or extended tube. it has tines and a slot in the bottom for the buffer detent to go into.
From appearances the buffer tube was not screwed in all the way. so I screwed in in the rest of the way. However now the stock wont lock into the first detent.... SMH... this poor gun needs some TLC.
So at this point I am not sure what to recommend. I'm honestly leaning towards suggesting he replace the buffer and buffer tube as he really seems to want to get rid of the sound. But again, I's making my best guess as to what is causing it based off some process of elimination testing. I can guarantee it will fix it.
I apologize in advance, the pics I took are not good.
As I got it, not screwed in enough?
After I screwed it in the rest of the way.
