I have one ARMS #19 Universal Weaver/STANAG QD throw-lever base for mounting various scopes on a flat-top receiver. This ARMS 19 has been used very slightly and is in excellent condition. Retail price is $140. I'll sell it for $85 including shipping by first-class mail.
I finally bought an ACOG TA31 so I don't need the ARMS 19 any longer. My e-mail address is email@example.com.
EDIT: the ARMS 19 is now SOLD pending receipt of funds.
