I have a 16" Double Star carbine gas Hbar barrel. The barrel is 1/9 twist, not chrome lined, and has seen between 500 and 1000 rounds. I believe closer to the 500 mark though. The feed ramps are rifle cut. Also included is a carbine gas tube and low profile gas block, I believe it to be YHM. All of this came off of a Double Star upper that I switched to a different barrel.
Would like to trade for PMags, Lancers, or good quality aluminum mags. Would prefer 20s but will also take 30s, or a combination of both. Let me know what you have.
