Tried searching for the answer but couldn’t find it.

Was at the LGS yesterday and was looking at SW AR’s. Both were identical in features, barrel twist and furniture. What struck me as odd was the two lowers were marked differently.

The first had the laser engraved M&P logo (very visible) on the mag well. The second just had an engraved SW logo in the left side of the receiver.

Again the rifles were identical otherwise but the one without the laser engraved logo was $100 cheaper.

Anyone know the difference ?

My Volunteer XV only has the S&W logo on the lower, no large M&P markings (very small M&P 15 though)...could be the difference between the Volunteer line and the M&P Sport
