M&P 15 used valves?

Wow. It's obviously a typo. "Used values" was intended.

Some folks here either fail to read carefully or think a new Sport is worth more than any used Smith AR, as the OP has stated he hasn't determined the model # and that it came with expensive third party sights (Troy?).

He may have made an excellent choice.

Whew! Good to know. I wasn't sure.

... or think a new Sport is worth more than any used Smith AR...

Well, a new Sport can be argued as the better value vs. used for most of the lineup. Unless you are getting a VTAC II, Mid MOE, 15TS, or 15T...

Look at it this way,

Barrel... Same 4140 steel, same twist rate, Sport is Melonite treated, others are chrome lined

BCG... exact same across the lineup

Those two items right there make up the heart of the rifle.

Trigger group... same across the lineup outside of the high end

If you are getting much of the same features at the same price new vs. used, why buy used?
