Accuracy hack

Comments found on Facebook M14/M1A groups.

1. "Can attest to this when I installed a ultimak rail. Gun was always a solid 2moa rifle but groups shrunk closer to 1.5ish.
   The ultimak gets HOT though. I was expecting some vertical stringing because the barrel and aluminum rail expand at different rates but I didn’t see that."
2. "I’ve used the m14 shgs on a criterion 16 inch std weight, and a Barnett 18.5 inch medium weight barrel. Both improved accuracy, but more improvement was with the std weight barrel than the medium. I do like the medium weight shg design better, though, as the rail atop extends the entire length of the hand guard."
