Will a Partisan Trigger lower work with a mid length Psa upper?

Too much coffee and not enough sleep. Bring on the insults. Note I will delete the nasty ones. The answer to that question, on further testing not seen in the video, is NO it doesn't work. 2 different Partisan trigger equpped lowers were tried with that upper. 3 different H3 buffers were tried. 2 different bolt assemblies, & 2 different buffer springs. With the 1st bolt assembly Spring combo, I got mid mag failure to feeds on 2 different Partisan equipped lowers using 3 different brands of H3 Buffers (Brownells, Spikes, and PWS). With the 2nd bolt assembly buffer spring combo, got 2nd round round dead triggers. Do note the 2 Partisan equipped lowers I have do work with standard carbine gas tube length uppers. Just not the mid-length gas tube upper.
