I am selling the .22 500mm STX barrel and pellet probe that came oem with my dreamline. The only thing missing to make a complete barrel swap kit is a magazine. Prior to switching to a 600mm I polished the 500mm and extensively tested the barrel. The barrel from my testing is capable of .25 - .4in 5 shot groups at 50 yards with 18gr jsb. Never had a chance to test at longer distances. The barrel cleaning periods were greatly extended with the polishing I performed. From my exp I can get around 2 500 round tins before accuracy drops ymmv. Unfortunately I bought my Dreamline from a retailer that locktites the moderator to the gun. From what I have seen/heard 15-30 secs with a heat gun and a nice twist should get it to come off relatively easily. Due to the inconvenience of having the moderator locktite on I will add the carbon fiber shroud that I bought to replace the OEM shroud. The carbon fiber will remove/greatly reduce POI shifts (from my exp with the 600). I am looking to get 225 shipped for the set.
