I have been using an Orga barrel with MDD hopup for a few months now. I can not say I love it, it took some work to replace the adjuster and get it so-so. Factory it was unusable, the adjuster was glued in place.
Currently range is good, out to 275 feet at 385 fps, but the ballistic window is about 6 feet. It hasn't improved really in the last few thousand rounds. I have some ideas regarding that. If FCC copied MDD, they will suffer similar results. I should try that Orga on a traditional chamber.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
