I had to look back to see what I posted in the 20" group buy thread.
I said there were a few bolt over base conditions.
Also, the bolt never locked open on an empty mag.
Doesn't bolt over base mean over gassing and not locking open on an empty mag mean undergassing?
If so, then I guess on average, it is just right.
