Finally got to see one on the new state legal Sport II's.
M&P(R)15 SPORT™ II - CA COMPLIANT* | Smith & Wesson
Local Sportsmans Warehouse had one on sale. Normal price was 669.99, with the sale price of 569.99. Grip looks and feels like my 10.00 Strike Industries. Buttstock is pinned, and no muzzle device. Muzzle is not threaded. Ambi safety, and no bullet button. Looks like all major brand AR's have gone featureless. As they had a Saint and an AR556 that were featureless as well.
