Is there a good source for specifications on Colt,Noveske,LMT,Etc. compared to others? I am new to AR's but not to firearms and manufacturing/machining and having trouble as an engineer finding the real value(not trade-in) for some of big name manufacturers. Comparitively some of the new comers seem to have better or equal fit and finish with same specs as others. Am I missing something? Looks like building a top notch AR is the way to go for as value. Is there an agreement from experienced folks on a complete rifle or made from different parts for each price range? Like Under $1k, 1-$2K, 2-$3K, 3-$4K, and up. I know you get what you pay for. Most the time. Wanna kill these ads? We can help!
