I have the MagPul version of the M&P 15-22 . The fol down sights alone were a big savings as they can be moved to anything w/ a picatinney rail.
At 50 Yrds it will shoot a hole in the paper about the size of a quarter. Trying to decide whether to buy the 15-22 Pistol (Looks fun to shoot) or the Custom Shop 15-22 w/ the threaded barrel and two-stage trigger. I really like that many of the parts are interchangeable w/ my ar-15 type guns. Even the trigger group. Great guns.
