Ive got a brand new, never been used MATECH Back Up Iron Sight for the AR15A3. No instruction sheet included, as I cant find it anymore.This has sat on my desk for 6 months, so I dont need it as bad as I thought I did when I bought it. $100 shipped in the CONUS, MOs or Paypal(add4%) accepted. Pics available via email.
Thanks for looking.
