Purchased a new spring and a Spikes Tactical type 2 heavy buffer. It cured about 80% of the problem. I am still having problems with stove piping, the last shell not bring eject. Per Montanas instructions, I tried Hornady 123gr Amax, and my reloads. Same story for both. At powder loads above 28.5gr CFE-223 I am getting pressure sign. Above 28.5 flattened primers, the shells are being tossed at the 1 o'clock position, and a small portion of the brass is getting mangled. I have contacted the barrel maker. I am going to look at a new adjustable gas system. I should have just spent the money on an already built upper. A2
Sounds like it is over gassed. I had an 18" AA barrel that was over gassed. My barrel wouldn't eject any cases , they would just stay in the chamber and jam. The good thing about an adjustable gas system is you can fine tune your loads for low recoil and reliability to a specific load if needed. You could have spent your money on a factory upper but you are now becoming a reluctant expert on the AR rifle system like many of us on the forum have become out of necessity LOL.
