I intend to purchase an AR-10 type rifle in the very near future. It is critical that I get this right. Spending this kind of $$ is a one time affair. My requirement is for an accurate, M4 carbine size implementation of the AR-10. I have come down to three contestants based on accuracy, reliability and cost. They are the LMT MWS, POF-USA R308-12-MRR-308 and the Amalite AR-10 Carbine. Please provide me with your rationale which one is the BEST VALUE based on my listed criteria. I appreciate your assistance in this most important decision.
