Stan "BigBamBoo" did an outstanding job with his side charging 9mm rifle. His rifle looks and functions great.
I bet there are other calguns member that has rifles that shoots pistol cartridges besides Stan and I. So please take pictures and tell us about it
My long term buddy purchased a HK USC45 awhile back. Ever since then, that .45acp rifle got me thinking something similar. About a month ago, I check out riflegears website and can't stop noticing a CMMG dedicated 9mm AR. So three weeks ago, my girl and I drove there. And I ended up DROSing that stripped lower. I took a couple of days researching parts. There seems to be four different 9mm twist configurations:
CMMG and RRA 1:10"
Model 1 Sales 1:15"
and Olympic Arms 1:16"
I ended up purchasing a Model 1 upper for it's twist rate.
CMMG 9mm lower,
Model 1 Sales 9mm upper with BCG "non ramped" and parts kit.
"note" Model 1 sales parts kit doesn't use mil-spec parts!
