The opinion of a Hypocrite (that's me):
What I say:
I'm another that says; wait for a deal on a M&P15OR. I got mine on a incredible deal from CDNN. $699-$100 rebate. I couldn't pass it up, and have absolutely no regrets.
The truth:
OK, actually in my case I had come very close to buying a 15OR for $800+, but decided I should wait another year before getting a 5.56 AR. Then the e-mail from CDNN came, moments later I was on the phone with them ordering a S&W M&P15OR. You'd think the next thought would have been, "did I just do that? Should I have just done that", but no, instead I squealed like a young girl "OMG I BOUGHT AN 15OR FOR ONLY $599 AND I"LL HAVE IT IN 2 DAYS, OMG OMG, OMG, ….. I NEED BULLETS!!!!!" and left for Wal-Mart.
In fact, I had no patience, but just dumb luck. So me saying you should be patient is a real hypocritical laugh. But, yea, .. err,. well, ..you should be patient.
Chromed barrel – cleans easier, lasts longer.
Dust cover – Keeps the crud out, but is also part of the AR experience. If buying an AR, I want a fully functional AR.
Forward Assist – Whole subject in itself. Not going to argue that here, but just like the dust cover I consider FA part of a modern AR, so I want it. Some others feel different.
