WOW...what a thread. I have read most of it...I'm just confused about one thing...
OLL...off list lower? What exactly does that mean?
I recently built an AR, and have been to the range a few times. However, just to be safe, even though I transport with a MAGVAULT (made by gunvault) inserted in the magwell, that I need to invest in some 10rd mags to be legal at the range.
Sadly, I did not realize that there is so much that makes these "illegal." I do have the "pistol grip" and the aforementioned rad-lock....damn...LOL
Again, thanks for the plethora of information, much appreciated.
