It looks like Slide Fire makes a stock for AR-15 & the M&P 15/22. My local Grady's has these stocks in stock, but I think they are for the AR-15. I asked an employee if the particular stock would fit the M&P 15/22, and he said yes, but he didn't look a day older than 16, and the older gentlemen couldn't tell me much either. They put it on an M&P15 not to be confused with the 15/22. Anyone know for sure? I'm wondering if both work, but the M&P15 version is the one that requires modification to fit ???
The standard AR will fit the M&P 15-22 I had one and after having Robbie Wheaton replace the trigger and add the muzzle break it ran flawlessly. If you are talking about Grady's in Anderson, save yourself some time and just call Robbie, he is in Powdersville.
