The first one was right out of the box.  Filled it and shot a string.

Second one is with Huma and some self tuning, though not certain it will stay this way and might not call it "well tuned"   ;D

Best i could come up with, playing energy vs efficiency, has been 3 mags at 15 foot pounds (24 shots). No "extra" parts, other than adjusting the transfer port to a slightly smaller size and fiddling around with the striker spring tension/stroke.

Not super efficient, but it's the most energy I can manage for 3 full mags with ll 24 shots inside a reasonable (4%) velocity variation.

Can get it to a higher efficiency at a lower speed, but nothing worth the effort for 4 mags (32 shots).  I kind of like running out of mags at the same time I need to refill.
