^ I agree, don't care about others opinions whatsoever. I don't want to see this post derailed with opinions. I like to see the truth/facts. With that said, the OP is asking for a round count. I believe that it is in regards to the sport model. My question/statement is that there are really not to many differences in certain M&P15's?. IE: I have a M&P15T with the same barrel. Different furniture, forward assist and dust cover. All internals from my understanding are the same. I was basically following this post because I would like to know if there are failure points if any to the M&P15 rifles, being that most are very similar. I will eventually use it for HD so reliability is quite important to me. I have just over 1k over two range sessions (cleaned in-between) with no FTF or FTE using a mix of XM855, XM193, M855 and federal BTHP. I shot hundreds of rounds of each type of ammo to ensure that there are no issues with it in my rifle then stashed the rest.

What aftermarket part?
