I am new to Ar's. I just picked up a dpsm 223 with eotech sight for a good price, Looking to add a couple more but have a couple questions.. 1) If you were to make a list of the top 5-7 stock 223 cal Ar's what order would they be, Your top 5 list. 2) Also I am a little gun shy on buying a weapon some guy built at home and not a factory build. I just a feel that the guy may have Micky moused it and i don't want to be the guy me dumped it on. Is this a realistic issue out there?.
