The sporter will shoot a .4" 3 shot group @ 50 yds. The AR clone will only do a 1 inch at that range simply because I'm using a holographic sight. That's good enough for me. Neither rifle was built for matches so it doesn't matter all that much. I'm more then happy with both's accuracy. I'm not as accuracy crazed as a lot of others. The sporter is very accurate to me but it is also an artistic extension of my personality.
Since it seems you mention the money invested here is a list of what has been done to it.
