I want to build a 9mm upper from parts. Can I use an ordinary upper receiver? Will an M4 receiver and M4 barrel extension work? Anything I have forgotten or do not know to ask? |
Custom SS barrel, mystery funshow flat top upper, std lower with M16 hammer made legal for AR use, and a std rifle buffer,,,, though I did gut mine and install a brass dowel to weight it to 7.0z, as I tend to use a suppressor, the dead weight helps keep more trash going out the front... and something to fill the large opening in the lower to jold them small 9mm mags ---  The "hammer" -- the one with the spring on it --
