As bad as people talk about DPMS (Panther Arms) I own one that I can shoot sub minute at over 300 m. Cost me 1100, but it's 5.56. The barrel is by far the most important part of the rifle for accuracy. A good barrel can run upwards of 500 dollars alone but most companies guarantee 1moa barrels Out of the box. Just have to do some research. Great website to get inexpensive, but reliable parts is cheaper than dirt . com I just finished building my first one and it's a dream. You're more than welcome to PM me and I'll help with whatever I can with my limited knowledge base.
