I have a like new Criterion Heavy Hybrid 22" 6.5 Creedmoor barrel, gas block and new handguard for sale. This fits the AR308/DPMS low profile upper. I got this in a trade and I'm pretty sure the barrel hasn't been shot. $375 shipped for all Venmo, PayPal f&f, cash, check or money order. Text is fastest. 512,2two7,49zero1
