Pin a flashider on it as well if it doesn't have one.
I used a pin on flash hider with H&K style front sight from Eagle, on my Mini and it shot noticeably better. For awhile I just thought that it was a better sight, but now I wonder if it doesn't help the barrel harmonics somewhat also. Do you think that's feasible? I've read about the struts, and add on gadgets to the barrel that helps the barrel harmonics to deliver better accuracy. I think I got lucky.
