| I ordered a commercial spec carbine buffer tube and noticed it was about an inch longer than a mil-spec buffer tube on another rifle. I was wondering if this was common and if the longer buffer tube requires any changes in the buffer used and if the longer buffer can create any function issues. Any info will be much appreciated. |
| Thanks for the clarification GhostRing. It's a DSA tube, Comm spec but not slanted. At first I thought it might be mil-spec since it was not slanted. I grabbed one of my AR's with a mil-spec stock and pulled the stock off and it would not go onto the new tube. I knew then it was Comm spec. I slid the Comm spec stock onto the new tube and noticed based off the last locking tab that the tube stuck out quite a bit more than I am used to. I screwed it onto my lower and did notice that the stock did not lock down as close to the lower as the shorter buffer tubes. This is the first time I ran into this. I recall reading an article where the author claimed he liked a particular brand of buffer tube because they ran a little longer. They did not say anything about the springs and buffers. So I started thinking, which may not be a good thing, about the issues with buffers and 9mm conversions. You need a longer buffer or a spacer in a carbine tube when running a 9mm upper to reduce the wear on the lower and its parts. So, I wanted to make sure I was not going to start breaking things with a longer buffer tube. Thanks! |
