My own experience is limited to the non nfa mech tech for a Glock 9mm and the Endo Tactical stock I ran on a PD's G18 (AWESOME BTW).

I would like to SBR a glock and put it in a CCU and would like your subjective opinions on the available choices.

AFAIK the choices include Hera, CAA, FAB/mako (same people?) what else am I missing?
