Hi all, first post here. I'm planning on shooting my first 3 gun match next month. I went and watched one last week and that was pretty much all it took to seal the deal. I had been reading up for a while and had already decided on a M3000 or M3K. I got a decent deal on a M3K and picked it up from my FFL yesterday. First off, I have never seen a gun with the internals so covered in oil as this one was. All I did was wipe all the excess off, shot in some CLP, and took it out today. 125 rounds of cheap Walmart Federal went through it without a single hiccup. I also put 5 slugs through it. They all shot point of aim out to 50 yards. I am honestly very impressed with this gun. I was ready to change out the extractor before I even got it, but I'm not sure if it's even necessary. It looks like I got a good one. I'm putting a 6+ extension on it as soon as MOA gets them in stock. Other than hogging out the load port and maybe some trigger work, is there anything else you'd recommend?
