LR-308 complete factory 'take off' AR-10 Barrel Assembly. Has the Gas Block, Flash Hider, Gas Tube, Barrel Nut, Bi Pod Stud and Free Float Hand guard. Less then 200 rounds fired. Barrel is Chrome Molly and has the 1-10 Twist Rate. I just re-barreled mine with a DPMS 24" Bull Barrel and no longer need these parts. All you need is an upper Receiver. Price is $225 and I will ship for $15. PM me with any questions.
