I have a Sig 556. It is an early model. It has a round count <300rds. It comes with original collapsable stock and tri-rail forearm. The rifle is basically just like it comes from Sig. No box, but comes with two sig mags that lock together. I'm interested in Olympic AR-15 in 9mm that uses Glock mags, H&K 45, H&K P7, or other 9mm AR's. Also take $1,000.00 cash. I ship to your FFL, You pay actual shipping. Call @ 901-574-9871 to discuss any trades or cash offers. I don't have time to PM back and forth.
