I have a like new (I am not sure if I even used either) set of two sight adjustment tools:
One is the one for the A-1
The second is the one for A-2
One is made by DPMS, and I am not sure of the manufacturer of the other.
I took these in on trading.
$20 shipped for both - priority mail
paypal balance transfers are fine, as are checks or m.o.s
email as I do not watch the board:
