So I bought this just as a fun gun. I wasn't expecting it to be amazing especially for the price. It's a Rock Island Armory Likn X4 semi-auto. It was around $300. It's actually pretty cool, fun to shoot. The trigger is definitely on the heavy side. It has a shell selector switch, 4 chokes. One of them is an extended "muzzle brake" or external turkey style choke. I've been running slugs through it at the indoor range. Probably only about 50-60 rounds. I'm getting a weird pitting or flaking in the barrel. It's never been in wet weather. I cleaned it well before shooting. Has
anyone ever seen anything like this. I hear their customer service is pretty good so I'll have to call and see what they say.
