I took advantage of Rifle Gearís gunsmithing services and had my S&W lower assembled with a DPMS lower parts kit and A2 stock kit. For $25 and a 48 hour turn around it was time and money well spent. Compared to my factory S&W Sport the trigger pull came out about the same, smooth and not gritty. Still looking for an upper so will try it out this weekend with the upper from my Sport after installing a bullet button.
Towards thee I roll, thou all-destroying but unconquering whale; to the last I grapple with thee; from hell's heart I stab at thee; for hate's sake I spit my last breath at thee.
