This is a speculation thread, haven't figured out what my next trade will be for, but I have been curious about AR's and looking into options. For about 650ish I could get that complete polymer lower that no one likes and a nicely equipped complete upper from PSA, but I know people recommend buying a complete rifle when getting into them. The M&P Sport seems like it would fit the bill, but I noticed it has no forward assist or dust cover. Would I miss those things? What else am I missing from a more spendier/higher end gun? Would I be happy for a good while until I got more spending money? I know it is seen as a good gun, but no one ever says what its missing to make it cheap.
