I would first take a look at the type of 3 gun matches you shoot or are in your area. If you are going to shoot mostly local bay type matches, you may want a shorter/lighter rifle than one you use for open terrain long range style matches. If you are going to shoot both, you may want one that compliments both style of matches. For bays 14.5" or 16" rifle with red dot vs. 16" or 18" with a LPVO. Whatever you go with spend the money where it counts: trigger, recoil system (adjustable gas, SCS, rifle length gas, etc.) Remember, you don't have to break the bank with high end name brand rifles. The upper and lower are only containers to put the good stuff inside of. Probably 99.9% of all rifle uppers/lowers are just fine right of the shelf. Also, you will be throwing this thing in muddy dump buckets, hitting tables, going prone in dirt, etc. It will will get beat up.
