Is that an out-of-the-box gun, or did you need to do any tweaking? Either way, congrats...and enjoy!
If you buy and sell enough guns, and properly test each one, you occasionally luck into a true gem. I recently did just that with a terrific Dominion Arms Socom, and I am now a firm believer in the old saying "It's better to be lucky than good!"
Now comes the true test: can you resist the idiotic compulsion, common among gun nuts, to sell or trade that gun off? We get a gun that shoots better than we have any right to expect, and then in a moment of weakness sell it when something else shiny comes along. Don't ask me how I know!
