So my setup was a DPMS Oracle with TR-25, PMAGs Gen II 30 round, bumpfire stock and Arklatex recoil rail.
I had never fired a bumpfire stock before. Not absolutely sure I did it right. It feels a bit odd but is absolutely controllable.
In the second video you can see how much I push the forend grip forward before the gun fires. You can adjust the resistance in the recoil rail and I will tighten that as it seems too soft for me, too much play
