TXforFreedom:

I did research it, actually I wanted the 'Raptor' since I have one on my M&P 15 and love it, but the risk of it not working and spending close to $100 was too much so I went with the BCM at about half the price and hoped for the best, if it did not work I was going to follow the tube demo. Bravo Company came up with a version two of the handle and its this version that is currently sold ...looks thicker on the end, plus and this is just me guessing the earlier bolt versions of the M&P 10 are little different than later productions, my rifle was made in Sept. 2013... loosened up tolerances maybe ... again just guessing don't quote me.
