About a month ago I placed an order for the LAR-10 Standard A4 with my FFL. However, now I am thinking that I would like to change that order to a LAR-10 Mid-Length A4. The reason for the change is because of what I plan on doing with it; I want to do 3 gun matches and I think that the Mid-Length is better suited to that. According to the RockRiverArms website, there isn't any difference in price. Additionally, the release of the LAR-10's are not scheduled for another six months (late summer). So, my question to you is: do you see any problems with changing the order?
