S&W M&P10 – More Observations

After posting my initial observations there were some more questions thrown out, all that I didn’t even think about covering in the first post, so I did a little research to get smart on the other .308 ARs by watching a cleaning video on youtube for the Armalite AR-10 and a few videos on the DPMS LR-308 so I could compare and contrast it the M&P10. While seeing these, I noticed a few more similarities and differences between the .308 ARs already on the market and M&P10.

The buffer looks a lot smaller than the Armalite AR-10’s buffer. I noticed the M&P10’s buffer was proportionately smaller than an AR15’s buffer to buffer spring, so I broke out an AR15 buffer to see how the M&P10’s buffer compares to it, and it is absolutely smaller than the Armalite AR-10 buffer. It looks like the same size as an AR15 buffer, but it may have weighed a little more (even though I did not do a precision weigh). ¬†This is in addition to being kind of beat up where I could tell it had hit the buffer retainer pin more than a few times. The picture I posted in my earlier review did a poor job of showing the wear on the buffer. ¬†Hopefully one of these two do a better job of showing the out of the box wear on the buffer.
