I have a front flip-up sight, tac latch, and SOG 7-position stock - all parts new. Some other ar15 parts available. Want to work a trade for Benchmade auto knives. I'm willing to do some cash too. Or purchase the Benchmade outright if the price is fair. Pics of my stuff available. Please e-mail me at firstname.lastname@example.org, or use the "Email User" link here.
