OKay, in the process of building an HBAR AR. Have a 20" barrel on the way. And have been thinking about using a side charging upper. As I am left eye dominant, I shoot from the left shoulder. I would like to use a left handed upper and bolt. Therein lies the question, I noticed just a brief blurb about the locking lugs on a barrel needing to be ambi for a left handed bolt to operate. Have any of you ran into this, and is it possible to do a modification to an existing barrel's lugs?
