Started getting failures to extract during some high-volume shooting w/ Wolf polymer. I had to tap most of these out with a rod. My AR hadn’t been cleaned thoroughly (like with the chamber brush and all) for a thousand or so rounds. So I cleaned it pretty good and took it out again today with some Wolf polymer and some Wolf brass cased. I got one failure to extract (on a brass cased round). I tried several pulls on the charging handle but no dice so I ended up tapping it out with a rod. That was out of 6 or 7 mags. Any suggestions? Hopefully this isn’t “normal” or “acceptable”. I am wondering if I need a more powerful extractor spring or if the one I have could be having trouble. |

from my expierence, its the wolf; that stuff just blows the carbon into the chamber and the casings get stuck, combined w/ low lube h/w, my problems have disappeared lately since i changed my extractor and added an O-ring and kept the BCG lubed (biggest factor i think)... |

I was having the same problem and it started after about 2k of wolf. After switching to brass case it still kept fte'ing. Turned out that I had a broken/cracked extractor pin. Changed it out, cracked again...same problem. I was on my third when I switched to a JP bolt and lost the problem all together. The original was a DPMS |
| I've found that Wolf cases, being steel, don't seem to expand and seal the chamber in quite the same way that brass does, allowing more fouling on chamber walls than usual. Then, after shooting a bunch of wolf, when I stick a brass cased round in it expands and then sticks on the wolf-related fouling, leading to FTE. I added a crane o-ring to the extractor and that seems to have solved the problem. |
Normal for Wolf IME. |
