    For anyone in the market for the M&P 15 Sport, it appears that they have changed the barrel. On another forum, two members posted that their recent purchases of the Sport came with a 1/9 twist barrel, vs. the 1/8 twist previously on the Sport. I called S&W customer support to confirm, and "Joe" advised that they have changed the spec, and that the Sport will now ship with a Melonite treated, 1/9 twist barrel. If you want the 1/8 twist barrel, you will need to purchase the M&P 15T.

    Still trying to confirm if it is still 5R rifling or if it is the traditional rifling.

    That's unfortunate. I thought using the 1/8 was a pretty ingenious decision. It's a great all-around twist rate.

    They are probably sourcing the Sport 1/9 barrels at a lower cost.

    I agree. The barrel was the high point of the rifle! Glad I got mine last year before they did this.

    Again, why dick around with something that works?

    Because someone was an idiot.

    Anyone know if S&W was doing the 1/8 barrels in house, or if they were outsourced?

    They were produced by Thompson Center, which S&W owns, from everything that I have read.

    Grant from G&R Tactical has also confirmed that there will be no more barrels with 5R rifling for the Sport. The 1:8 twist with 5R rifling barrels are being held for the "premium" lines, the VTAC II, the MOE, and the 15T.

    Grant said that the S&W rep told him the reason for the change is the 5R rifled barrels were a production bottleneck and no one wants to make them.
