Just picked up a new M40 A1 2nite. It's got the manual safety on it. Not used to the setup. Any body know if the manual safety gets in the way, accidentally set off etc? It feels really great. Cleaned it up as best I could with FP-10 and stuffed 20 rounds in the mags to get 'em all worked in. Range report(hopefully) Saturday afternoon. Also anyone know where I can get hi-cap mags? Great looking forum will be spending much time here.
