Congratulations. You have a very nice setup.
Last year, I bought a Spikes Mid-Length dedicated .22lr upper and put it on a RRA lower with a two stage trigger. Since, I put a winter trigger guard on it and a Magpul MOE handguard.
I think these are very sweet shooting uppers. At the shooting club that I belong to, this year they added a new event for the club. Itís a CMP Sponsored Sporting .22lr competition. I am signed up for the first relay.
I will be using my Spikes/RRA rifle at that event.
