Yep, this is one of the older M&P-15s not the Sport or Sport II model since it has the forward assist and dust cover and those models don't. This is of course assuming that's the same upper that came with the lower from the factory or that it isn't a build that just used an M&P 15 lower.I have one also I believe the model is mp-15. I guess you can say yours is the 2nd gen. Mine is the 1st run called Sporter model that doesn't have the dust cover or forward assist. The sw shoots everything I put in it. I can't say the same about the Ruger ar15
The Sport II's have the FA and dust cover.Yep, this is one of the older M&P-15s not the Sport or Sport II model since it has the forward assist and dust cover and those models don't.
