Looking at different build options and deciding what type of upper to order from Mega Arms. I'm leaning towards their new monolithic MA-10 upper but I'm starting to think about the extra weight. Accuracy is my primary goal for this build but it has to be light enough to be practical. Is a monolithic upper a big accuracy advantage? Is the accuracy gained worth the extra weight? Would a standard upper and free float handguard combination be just as accurate? Any opinions and real world experience would be appreciated. Thanks.
