I took the barrel, shroud and moderator apart tonight. Then, I made a video and some photos with the bore scope before I cleaned and polished the barrel. Disassembly was very easy. There was a liberal amount of red thread locker present. As suspected from the first inspection with the bore scope, there is a relatively thick layer of cosomoline in the bore, especially near the breech. Not a big deal, it's there to protect the barrel from rust, but should be removed before shooting if you want the maximum accuracy. I slugged the barrel. My barrel is bored at .2175 a nice standard bore. I've read somewhere that the bore is unchoked, but I measured a slight choke of .21675. But without using an "Air Gap" measuring device, I'm not sure how accurate my measurements are. Maybe
@AirVenturi will be nice enough to confirm whether or not the barrel is choked. So far, I'm not finding anything that I don't like for the price. It's been too windy to shoot today. The weather is weird, it was 78f yesterday and in the fifties today and in the forties tomorrow.
Before and after cleaning/polishing.
