One is a 12" carbon fiber, one is a 12" aluminum and the other is a 15" aluminum
The test lower is a SI defense with a rifle buffer and spring, PRS stock and a Geissele SSE trigger We have also tested this with a standard DPMS lower and it functioned fine. We have had good luck with Magpul Pmgs but the flex in the polymer only allows three rounds to be loaded without issue.
$1400 located in the Orland Area.
