Its been a while, but I started thinking about it again so I figured I would see what INGO's experts thought.
I have a Bushmaster XM-15. Nothin fancy, just a run of the mill AR. I added a clamp on 3 rail block to the barrel. No big deal until... I took it to an appleseed.
Long story short my shots were all over the place. Just as I would get my sights adjusted, my rounds would take off in another direction. I never did get it under control, and even spent several sessions doing my own thing to work on my zero instead of running the AQT string. The second day it was the same; just as I would get it zeroed, as the gun heated up, my zero would change significantly and the more I shot the worse the POI would change. (and it seemed to get slightly better after a break such as story time, but would go back to awful after shooting a bit)
Here is my question: would clamping something onto the barrel cause accuracy issues? My thought is the clamped item would absorb heat and cause the barrel to heat irregularly and therefore warp a bit. or am I smoking crack?
Not the exact item, but here is what I am talking about.
