In tricking out my 10/22 the only part I had left to add was a bull barrel. It ran 100% as-is, even when extremely fouled up. I added a 16" .920 barrel and wow, does it look amazing! Well, I went out yesterday and was having excessive amounts of misfires, failure to extract, etc..... and the only thing I did was switch out the barrel. It appears to be lined up properly- that being the extractor cut and the extractor itself. I know it's more than likely something simple that I didn't do properly as this was my first attempt. I watched some video on youtube and it looked so simple. I was a little put out seeing it was totally reliable before and after became a lemon. I appreciate any input guys, I know I can't be the first guy to have issues. Thanks in advance.
