With the way I have my Tier 1-2 platforms set up with hand stops now (AFGs are in the parts box with all the other stuff that was the rage at times then faded away) I still can't get a full support arm lock-out (an 18 or 20" barrel length handguard comes close) but I still have far better support than the AFGs and back-in-the day VFGs.Almost everyone is actually using a C clamp. Lots of people use a very exaggerated version of it.
I think I may have one Tier 3 ban-era AR with an AFG on it.
I've tried to simplify the extras on the guns to only those that are essentially useful and to cut down on weight and bulk.
But to each his/her/its own...
