I have a 20 inch proof research carbon fiber Barrel in an AR-15 upper with 17 inch handguard. 100 rounds of factory 55 grain ammo and new brass and some used brass. Can include scope and mount if wanted. It's a Sig Tango 4x24. $800 for upper with carbon barrel and 17-in handguard without bolt carrier and charging handle. It will use a standard 556 bolt carrier. $1,100 with scope and ssalt mount. All brass and loaded ammo go with upper regardless if you take the scope amount or not. Thanks great coyote gun.
