I bought a 10.5" gen 2 brn180 for $300 today. The dude said the gas system had seized on suppressed. The upper was otherwise in good condition. I just got druk and punched the entire gas lever out. New gas assemblies are $70 on brownells, or I could clean this one and try putting it back in. Which should I do?
Also is this upper any good? I couldn't give less of a shit over piston vs DI but I love the AR-18 for historical reasons
