Custom AR15

Selling my 18inch cold hammer forged ar-15, Anderson upper and lower, BCM furniture(hand grip w/storage, vertical forward grip w/storage and BCM 15inch mlok hand guard. Ambitious safety and ambi raptor CH. 1-8 twist ARP barrel, birdcage flash hider, Great single stage duplex bow trigger, Great for distance shooting. Curved with flat section for two different trigger pulls. Shoots out to 600 yards easy with right optic and 70gr+ ammo. Very light recoil. Has a total of 1200ish Rounds shot. Everything is in perfect working order. Very minor wear. Always cleaned after every use and in really great shape. The build was $1500 selling for $1150 obo. I'm looking to get a AR10 instead. Willing to trade for a equally nice 308 AR build or just cash. Would be willing to trade gun and some cash for the right AR10 308/7.62 Nato build. I'm in Boise, will come with a 30rd pmag and I could toss in my Caldwell adjustable 5-9inch mlok bipod for the right price. Only getting rid of this because I recently got a 16inch Ar15...so wanna get a 308 18 or 20 inch.
