One Matech BUIS for sale. I bought it new, opened the package but never installed it (the red threadlock agent is still on the screw showing it has never been installed). The original packaging, instructions, and all pieces are included. pic of sight
$100 shipped USPS priority to the US only. Payment only by US postal money order or paypal (no credit cards; my account can not accept them at all).
Post "I'll take it" here or send an IM to purchase the sight.
Trades considered: a Pact shot timer (Club 2 or 3 model) or a good quality B/BC/CH set for an AR-15.
