I am in the market to buy a 308 in the AR-10 platform. I want a 16" bbl and would prefer a Mid-length. I will shoot this rifle suppressed some of the time. I would like an adj gas block. Although money is an issue to a point it isn't. I plan on keeping this rifle and want one that is completely reliable and accurate. I expect 3/4moa accuracy at 100yds. In past I have owned several Armalite's but never wanted to hang on to one. I am a fan of Rock Rivers but do not want the FN/Fal mags. I have researched the LMT MWS systems and they do appeal to me. Also the Knight's SR-25 rifles. I do want a rifle that will handle the Magpul Pmags. Am leaning towards the LMT because I can use same lower and multi-caliber the uppers. I like the Magpul UBR stocks but that could be added on later. I like the visual of the POF but a friend of mine who is very knowledgable is not a fan of them at all. What would you choose and why. I know there is a fan base of piston driven vs gas and I am open minded to both. Thanks! krw
